“Policeman’s heel” is a traditional term for heel pain associated with prolonged walking and standing, particularly on hard urban surfaces. Although it is most often used today as a colloquial name for plantar fasciitis, the historical literature also used it to describe plantar calcaneal bursitis or bruising of the calcaneal fat pad after repetitive heel strikes or a fall. Understanding the term therefore requires attention to both its historical origins and its modern clinical usage.

Historical origins

The expression likely arose in the era when police officers patrolled city streets on foot for long shifts. Repeated impact on concrete and asphalt, combined with stiff regulation footwear and limited opportunity to rest, made heel pain a common occupational complaint. The name persisted because it vividly captured the link between occupation, repetitive loading, and pain beneath the heel.

However, “policeman’s heel” is not a precise diagnostic label. A 1981 BMJ article used the term in the context of plantar calcaneal bursitis, while later clinical teaching has described it as inflammation of the bursa beneath the calcaneus or a contusion of the heel fat pad following repetitive bounding, jumping, or landing on the heel. In contemporary patient-facing usage, it is more commonly equated with plantar fasciitis. This terminological overlap is clinically important: the management of fascial overload differs in emphasis from the management of a fat-pad contusion or an inflamed calcaneal bursa

Anatomy and pathophysiology

The plantar fascia is a thick fibrous aponeurosis arising mainly from the medial calcaneal tubercle and passing forward to the toes. It supports the medial longitudinal arch and contributes to the windlass mechanism, in which dorsiflexion of the toes increases arch height during the propulsive phase of gait. Because it transmits substantial tensile load with every step, it is vulnerable to repetitive overload.

In plantar fasciitis—more accurately described in many cases as plantar fasciopathy—the fascia is subjected to load beyond its adaptive capacity. This produces microtearing, collagen disorganisation, thickening, and degenerative change near its calcaneal origin. Although the suffix “-itis” implies inflammation, chronic cases often show degenerative rather than purely inflammatory pathology. This distinction explains why anti-inflammatory treatment alone may relieve symptoms temporarily but does not necessarily resolve the underlying tissue problem.

By contrast, plantar calcaneal bursitis involves irritation of a fluid-filled bursa beneath the heel, while fat-pad contusion results from compression and displacement of the protective adipose tissue under the calcaneus. In these presentations, pain is more directly related to heel impact and may be aggravated by walking barefoot on hard floors, jumping, or landing heavily on the heel

Risk factors

Policeman’s heel is fundamentally a load-related condition. Prolonged standing, long walking shifts, running on hard surfaces, and sudden increases in training volume all increase cumulative plantar fascia and heel-pad stress. Occupations requiring extended time on foot—including policing, nursing, teaching, retail, and warehouse work—remain relevant risk settings.

Intrinsic factors also influence susceptibility. Reduced ankle dorsiflexion from gastrocnemius–soleus or Achilles tightness can increase strain through the plantar fascia during gait. Foot posture may contribute: both pes planus and pes cavus can alter load distribution across the foot. Increased body mass raises the mechanical demand placed on the heel and fascia with each step, while age-related loss of tissue elasticity may reduce tolerance to repetitive loading.

Footwear is another major extrinsic factor. Shoes with inadequate cushioning, poor arch support, or a stiff, worn-out sole can transfer more impact to the heel and reduce the foot’s capacity to dissipate force. For runners, abrupt changes in mileage, terrain, or footwear can precipitate symptoms; for occupational walkers, hard floors and insufficient recovery time may have the same effect.

Clinical presentation

The classic presentation of plantar fasciopathy is sharp, stabbing pain at the medial plantar heel, often radiating into the arch. Pain is typically worst with the first steps in the morning or after prolonged sitting—the so-called “first-step pain.” As the tissue warms up, discomfort may ease, only to return after extended standing, walking, or exercise.

Examination usually reveals focal tenderness over the medial calcaneal tubercle. The windlass test, performed by dorsiflexing the toes to tension the plantar fascia, may reproduce symptoms. Pain after rather than during activity, together with morning stiffness, supports a diagnosis of fascial overload. In fat-pad bruising or calcaneal bursitis, tenderness may be more central beneath the heel and more closely linked to direct impact.

Clinicians should also consider differential diagnoses. Calcaneal stress fracture should be suspected with progressive pain, particularly in runners or people with low energy availability. Achilles insertional tendinopathy produces posterior heel pain, while tarsal tunnel syndrome may cause burning or neuralgic symptoms. Red flags such as trauma, fever, night pain, systemic illness, or suspected infection warrant further investigation. Imaging is not routinely required but may include radiographs, ultrasound, or MRI when the diagnosis is unclear or symptoms persist.

Conservative management

Most cases of policeman’s heel improve with structured conservative care. The first principle is load management: reduce aggravating activity, avoid barefoot walking on hard floors, and modify occupational or sporting exposure while maintaining fitness through lower-impact alternatives such as cycling or swimming. Complete rest is rarely necessary or practical; the goal is to reduce load to a level the tissue can tolerate.

Stretching is a cornerstone of treatment. Regular calf and Achilles stretching improves ankle dorsiflexion and reduces tensile demand on the plantar fascia. Plantar fascia-specific stretching, often performed by pulling the toes into dorsiflexion and massaging the arch, can also reduce first-step pain. Strengthening of the intrinsic foot muscles, calf complex, and hip stabilisers may improve load tolerance and gait mechanics over time.

Footwear and orthoses play an important role. Supportive shoes with cushioned heels and appropriate arch contour can reduce impact and fascial strain. Prefabricated or custom orthoses may redistribute plantar pressure and support the medial arch, although the best device depends on foot posture, symptoms, and activity demands. Taping can provide short-term symptom relief by limiting fascial strain during activity.

Symptom relief may include ice after activity and short-term use of non-steroidal anti-inflammatory drugs where clinically appropriate. Night splints, which maintain gentle dorsiflexion during sleep, can help patients with pronounced morning pain. For persistent cases, clinicians may consider physical therapy, extracorporeal shockwave therapy, or corticosteroid injection. Injections can provide short-term relief but carry a recognised risk of plantar fascia rupture and fat-pad atrophy, so they should be used judiciously.

Prognosis and prevention

The prognosis for policeman’s heel is generally good. Many patients improve substantially with consistent conservative management, although recovery may take months rather than weeks, particularly when the condition has become chronic. Recurrence is more likely when the underlying contributors—calf tightness, unsuitable footwear, excessive occupational standing, or abrupt training progression—are not addressed.

Prevention emphasises gradual loading, appropriate footwear, and early attention to symptoms. Workers who spend long hours on hard surfaces benefit from cushioned insoles, supportive footwear, and regular breaks from static standing. Runners should increase training volume progressively and replace shoes before cushioning and support deteriorate. For people with recurrent heel pain, maintaining calf flexibility and foot strength is a sensible long-term strategy.

Policeman’s heel is a historically evocative term that captures the relationship between repetitive heel loading and plantar heel pain. Although commonly used to mean plantar fasciitis, it has also described calcaneal bursitis and fat-pad contusion, reminding clinicians to assess the precise source of pain rather than relying on a label alone. Effective management combines load modification, stretching and strengthening, supportive footwear or orthoses, and, when needed, targeted adjunctive therapies. With a structured, patient-centred approach, most people with this condition can return to comfortable walking, work, and running.

Post-static dyskinesia is the characteristic pain, stiffness, and altered gait that occurs during the first steps after a period of non-weight-bearing rest. Although most commonly associated with plantar heel pain or plantar fasciopathy, it is best understood as a clinical pattern rather than a diagnosis in itself: it signals that a pain-generating structure in the foot or ankle has been held in a shortened or unloaded position and is then rapidly loaded on standing.

Definition and Clinical Presentation

The term post-static dyskinesia literally describes “pain after static posture.” Patients typically report sharp, stabbing, or burning pain beneath the heel—often at the medial calcaneal tubercle—when rising from bed in the morning or standing after prolonged sitting, driving, or watching television. The discomfort usually eases after several minutes of walking, only to recur after the next period of rest.

This “first-step pain” is one of the most useful historical clues in heel pain assessment. In plantar fasciopathy, pain commonly improves with gentle activity as the tissues warm and become more compliant, then may worsen again with prolonged standing, walking, running, stairs, or push-off. The pattern therefore differs from many mechanical or inflammatory conditions in which pain steadily increases with activity.[

Patients often adopt a guarded gait during the painful first steps: reduced heel loading, shortened stride, avoidance of terminal push-off, or temporary weight shift to the contralateral limb. Although protective in the short term, this altered gait may increase load elsewhere in the foot, ankle, knee, or hip if it persists.

Pathophysiology

The dominant explanation for post-static dyskinesia in plantar heel pain relates to the plantar fascia and its role in the windlass mechanism. During rest—particularly sleep—the ankle often rests in relative plantarflexion and the toes are not actively dorsiflexed. In this position, the plantar fascia and calf-Achilles complex are held in a comparatively shortened state.

On standing, body weight is rapidly transferred through the foot. The ankle moves toward dorsiflexion, the arch lowers under load, and toe extension engages the windlass mechanism, increasing tension in the plantar fascia. If the fascia is degenerated, stiff, or sensitised, this abrupt transition from low tension to high tensile load can provoke intense nociceptive pain.

Histologically, chronic plantar heel pain is more accurately described as plantar fasciosis or plantar fasciopathy than as pure inflammation. Repetitive tensile overload may produce collagen disorganisation, mucoid degeneration, thickening, and reduced tissue tolerance at the fascial origin. The morning pain therefore reflects both mechanical strain on a poorly tolerant tissue and local nociceptor sensitisation.

Reduced ankle dorsiflexion is clinically important because it increases demand on the plantar fascia during gait. A tight gastrocnemius-soleus complex, limited first metatarsophalangeal joint dorsiflexion, prolonged standing, sudden increases in activity, unsupportive footwear, and occupations involving long periods on hard surfaces can all contribute to fascial overload.

Differential Diagnosis

Although post-static dyskinesia strongly suggests plantar fasciopathy, it is not pathognomonic. Nerve-related plantar heel pain, including entrapment of the first branch of the lateral plantar nerve—sometimes termed Baxter’s neuropathy—can also produce marked pain after rest. In neural compression, symptoms may ease with movement and ambulation, whereas fascial pain may initially improve but later increase with sustained load.

Other causes of heel pain should be considered, including calcaneal stress fracture, fat-pad atrophy or contusion, Achilles insertional tendinopathy, retrocalcaneal bursitis, seronegative inflammatory arthropathy, and, less commonly, tumour or infection. A careful history and examination remain essential: point tenderness at the medial calcaneal tubercle supports plantar fasciopathy, whereas diffuse heel tenderness, night pain, swelling, systemic symptoms, or pain that fails to improve with conservative care warrants further investigation.

Clinical Assessment

Assessment should begin by reproducing and characterising the symptom pattern. The clinician should establish whether pain occurs specifically after rest, how long it takes to settle, whether it improves or worsens with walking, and whether it returns later in the day. Palpation of the medial calcaneal tubercle, plantar fascia, Achilles insertion, and potential nerve entrapment sites helps localise the source.

The windlass test can be useful: dorsiflexion of the hallux increases tension through the plantar fascia and may reproduce medial arch or heel pain. Assessment should also include ankle joint range of motion, gastrocnemius and soleus flexibility, subtalar and midtarsal mobility, foot posture, footwear inspection, and observation of gait.

Imaging is not routinely required for typical plantar heel pain but may be appropriate when presentation is atypical, trauma is reported, or symptoms persist despite appropriate management. Weight-bearing radiographs can identify structural contributors, while ultrasound or MRI may demonstrate plantar fascial thickening, tears, or alternative pathology.

Management Implications

Post-static dyskinesia provides a practical treatment target: reduce the abrupt tensile load placed on sensitised tissue at the transition from rest to weight bearing. Initial management commonly includes activity modification, relative rest from aggravating loading, footwear with adequate heel cushioning and arch support, and short-term taping or offloading where appropriate.

Stretching is central to conservative care. Calf and plantar fascia stretching may improve tissue extensibility and reduce the sudden strain experienced on first standing. Night splinting can maintain the ankle and toes in a more dorsiflexed position overnight, reducing the shortening that occurs during sleep and therefore lessening first-step pain.

Orthotic therapy may be useful when excessive pronation, poor shock absorption, or high plantar pressures contribute to symptoms. Footwear changes, heel cups, cushioned insoles, and supportive arch contours can reduce fascial strain. For persistent cases, clinicians may consider extracorporeal shockwave therapy, corticosteroid injection used cautiously, or, rarely, surgical release after failure of structured conservative treatment.

Patient Education

Patients should understand that post-static dyskinesia is not merely “morning pain”; it is a load-sensitive symptom that can occur after any prolonged period of sitting or inactivity. Explaining why the first steps hurt—and why gradual movement often relieves them—improves adherence to stretching, footwear modification, and graded return to activity.

Early intervention is preferable. If untreated, repeated sudden loading of a sensitised plantar fascia may perpetuate the pain cycle, alter gait, and make symptoms more persistent. A structured programme addressing tissue capacity, calf flexibility, foot strength, load management, and footwear is generally more effective than passive treatment alone.

Post-static dyskinesia is a hallmark clinical feature of plantar heel pain, particularly plantar fasciopathy. It arises when a shortened, stiff, or sensitised plantar fascia is abruptly loaded during the first steps after rest. Recognising this pattern assists diagnosis, guides examination, and informs conservative management aimed at reducing initial tensile strain, improving tissue tolerance, and restoring comfortable gait.

The PediRoller is a small, ridged foot-rolling device designed to provide self-massage and stretching to the plantar surface of the foot. It is commonly used for temporary relief of heel and arch discomfort, tired feet, and symptoms associated with plantar heel pain or plantar fasciitis. Used appropriately, it may be a useful adjunct to a broader management programme, although it should not be regarded as a stand-alone treatment for every cause of foot pain. The manufacturer recommends rolling the foot from the heel towards the arch for approximately three to five minutes, twice daily.

Purpose and mechanism

The plantar fascia is a strong band of connective tissue extending from the calcaneal tuberosity towards the forefoot. It contributes to the maintenance of the medial longitudinal arch and assists with efficient force transmission during walking and running. When the plantar tissues are overloaded, patients may develop localised heel pain, arch discomfort, or stiffness during the first steps after rest.

The PediRoller acts through two principal mechanisms. First, the ridged surface produces a form of mechanical massage as the foot is rolled over it. This may reduce the subjective sensation of muscular tension and provide short-term analgesic relief through sensory stimulation. Second, the repeated movement places gentle pressure through the plantar soft tissues and may temporarily improve their tolerance to loading and perceived flexibility. Commercial information describes the device as helping to stretch the plantar fascia and massage tired feet, although claims of improved circulation or tissue healing should be interpreted cautiously.

The device may also be chilled or frozen before use. Cooling can provide a counter-irritant effect and may be soothing when symptoms are irritable after activity. However, cold application should be controlled carefully. A frozen device should not remain stationary against the skin, because prolonged local cooling may cause discomfort or cold injury. Continuous movement and an appropriate protective layer are sensible precautions, particularly in people with reduced sensation.

Preparation for use

Before using the PediRoller, the patient should inspect the plantar skin for cuts, blisters, fissures, ulceration, bruising, or signs of infection. The roller should be clean, intact, and placed on a stable floor. A seated position is generally preferable initially because it allows the patient to regulate pressure and reduces the risk of excessive loading.

The patient can begin with the device at room temperature. If a cold application is desired, the roller may be chilled or frozen according to the product instructions. It should be wiped dry before use to prevent slipping. Patients should avoid applying excessive force in an attempt to obtain faster results. The objective is controlled, tolerable pressure rather than aggressive treatment.

The foot should be placed over the roller with the roller positioned beneath the plantar surface. The patient then moves the foot slowly backwards and forwards, generally from the heel towards the arch and forefoot. Some product guidance recommends a continuous movement from the heel to the ball of the foot, while other instructions focus primarily on the heel-to-arch region. The most appropriate range should be determined by symptoms: painful areas may be approached gently, but the patient should not repeatedly provoke sharp or escalating pain.

Recommended technique

A practical introductory programme is three to five minutes per foot, once or twice daily. Many patients find it convenient to use the PediRoller before their first steps in the morning, after prolonged sitting, or following activity. Morning use may be particularly attractive for individuals who experience pronounced first-step pain, although the roller should not replace a structured stretching and strengthening programme.

The movement should be slow and rhythmic. Pressure can initially be supplied mainly by the weight of the leg, with progression towards partial standing only if the patient can tolerate it without symptom exacerbation. A useful pain-monitoring approach is to maintain discomfort at a mild, acceptable level and to assess the response later that day and the following morning. If symptoms become substantially worse, the duration or pressure should be reduced.

The device should not be used by repeatedly pivoting on one painful point. Instead, the foot should move across the roller so that pressure is distributed through the plantar tissues. The patient may also vary the position slightly to address the medial arch, central plantar region, and forefoot, provided that this does not reproduce neurological symptoms or intense local pain.

Clinical role and limitations

The PediRoller is best considered a symptom-modifying intervention. It may help a patient feel more comfortable and may improve short-term tolerance of walking or exercise. It is unlikely, by itself, to correct contributing factors such as sudden increases in running volume, reduced calf flexibility, weakness of the intrinsic foot muscles, inappropriate footwear, impaired load management, or proximal biomechanical deficits.

For plantar heel pain, rolling may therefore be combined with education, activity modification, supportive footwear, calf and plantar fascia stretching, progressive strengthening, and—in selected cases—taping, orthoses, or other interventions. The appropriate programme depends on the diagnosis. Heel pain can arise from conditions other than plantar fasciitis, including calcaneal stress injury, nerve irritation, fat-pad disorders, inflammatory arthropathy, tendinopathy, or referred pain. Persistent or atypical symptoms should prompt clinical assessment rather than prolonged unsupervised rolling.

The evidence for self-massage and rolling is more supportive of short-term symptom relief than of a definitive cure. Consequently, clinicians should explain that improvement may be gradual and that treatment should be guided by function, irritability, and response to loading. A patient who experiences temporary relief but continues to overload the foot may obtain only limited long-term benefit.

Safety considerations

People with diabetes, peripheral neuropathy, peripheral arterial disease, significant circulatory impairment, or reduced protective sensation should seek professional advice before using the device. The product guidance specifically advises caution for people with diabetes or circulatory disorders and states that it should not be used on broken skin. Patients with these conditions may not accurately perceive excessive pressure, cold injury, or tissue damage.

Use should also be avoided over acute wounds, infection, marked swelling of unknown cause, or severe bruising. A clinician should assess symptoms that are associated with numbness, burning, weakness, night pain, unexplained swelling, systemic illness, or an inability to bear weight. If rolling causes increasing pain, skin irritation, bruising, or symptoms that persist after use, it should be discontinued and reviewed.

After use, the roller can generally be cleaned with warm soapy water and dried thoroughly. Hygiene is particularly important when the device is shared or used in a clinical setting. Patients should receive clear instructions on pressure, duration, cold application, and warning signs rather than being told simply to “roll the foot.”

The PediRoller offers a convenient method of self-massage for people with tired feet, arch discomfort, and some forms of plantar heel pain. Its ridged surface and rolling action may reduce perceived tension and provide short-term comfort, while optional cooling may be soothing during an irritable episode. The recommended technique is slow, controlled rolling beneath the foot for approximately three to five minutes, usually twice daily.

Its greatest value is as an adjunct to comprehensive care. Effective management should address diagnosis, tissue loading, footwear, strength, flexibility, and patient-specific risk factors. Used within those limits—and with appropriate precautions—the PediRoller can be a simple, inexpensive tool that helps patients participate actively in their foot-care programme.

Posterior tibial tendon dysfunction (PTTD) is a progressive disorder involving failure of the tibialis posterior tendon and, frequently, the supporting ligaments and joints of the medial foot and ankle. It is a major cause of adult-acquired flatfoot and may produce pain, weakness, loss of the medial longitudinal arch, hindfoot valgus, forefoot abduction and, in advanced cases, ankle valgus. Because the deformity reflects a three-dimensional failure of the foot rather than an isolated tendon problem, the term progressive collapsing foot deformity (PCFD) is now increasingly preferred.

Anatomy and pathophysiology

The tibialis posterior muscle originates mainly from the posterior tibia, fibula and interosseous membrane. Its tendon passes behind the medial malleolus, changes direction around the ankle, and inserts primarily onto the navicular, with expansions to the cuneiforms, cuboid, metatarsal bases and sustentaculum tali. It contributes to inversion and plantarflexion and is an important dynamic stabiliser of the medial longitudinal arch.

During stance, the tendon assists in controlling pronation and helps convert the foot into a rigid lever for propulsion. Tendon degeneration, elongation or rupture reduces this support. The spring ligament, deltoid ligament, plantar fascia and other passive stabilisers may subsequently become overloaded. The result is progressive pronation, hindfoot eversion, talar plantarflexion and adduction, forefoot abduction, and collapse of the medial arch.

The condition is most common in middle-aged and older adults, particularly women, although it also occurs in athletes and younger patients. Reported risk factors include obesity, hypertension, diabetes, previous trauma, inflammatory disease and corticosteroid exposure. Mechanical overload is often compounded by reduced calf strength, impaired balance, poor proximal limb control and limited ankle dorsiflexion.

Clinical presentation

Symptoms commonly begin with pain and swelling along the posteromedial ankle, especially behind or below the medial malleolus. Patients may describe fatigue, aching during prolonged standing or walking, and difficulty walking on uneven ground. As the deformity progresses, pain may shift to the lateral hindfoot because of sinus tarsi or subfibular impingement.

Clinical assessment should compare both limbs and include standing alignment, gait, footwear, ankle range of motion, hindfoot position and the ability to perform a single-leg heel rise. Important findings include:

• Tenderness or swelling along the tibialis posterior tendon.
• Reduced inversion strength and pain with resisted inversion.
• Loss or flattening of the medial longitudinal arch.
• Hindfoot valgus and forefoot abduction.
• The “too-many-toes” sign, reflecting lateral displacement of the forefoot when viewed from behind.
• Difficulty or inability to perform a repeated single-leg heel raise.
• Reduced inversion of the calcaneus during heel elevation.
• Limited ankle dorsiflexion or gastrocnemius tightness.

The single-leg heel-rise test is particularly useful. In early disease, the patient may complete the movement but experience pain or weakness. In more advanced disease, the patient cannot elevate the heel or cannot invert the hindfoot during the maneuver. Nevertheless, clinical testing should not be interpreted in isolation, since pain, balance impairment and coexisting ankle pathology may influence performance.

Diagnosis and classification

Diagnosis is primarily clinical, supported by weight-bearing imaging when deformity is suspected. Plain radiographs should generally include weight-bearing anteroposterior, lateral and hindfoot views. They can demonstrate loss of arch height, increased talonavicular uncoverage, forefoot abduction, talar–first metatarsal malalignment and hindfoot valgus. Stress or specialist imaging may be useful when ankle instability or rigid deformity is present.

Ultrasound can assess tendon thickening, tenosynovitis, partial tears and dynamic function. Magnetic resonance imaging is valuable when the diagnosis is uncertain or when tendon, spring ligament, deltoid ligament, cartilage and occult bone pathology must be evaluated. However, imaging abnormalities should be correlated with symptoms and physical findings.

Traditional staging systems describe a continuum from painful tendon dysfunction without major deformity to flexible flatfoot and finally rigid deformity with ankle involvement. The newer PCFD classification recognises that several deformities may coexist and that flexibility is clinically important. Class A represents hindfoot valgus; class B, midfoot or forefoot abduction; class C, forefoot varus or medial-column instability; class D, peritalar subluxation or dislocation; and class E, ankle instability or valgus tilt. Each deformity may be flexible or rigid.

This framework is clinically useful because treatment should address the dominant deformity and its flexibility, rather than assuming that tendon failure follows one predictable sequence.

Conservative management

Early treatment is usually non-operative. The goals are to reduce tendon load, control deformity, restore strength and improve function. Relative rest and temporary modification of aggravating activities may be required, while complete immobilisation should generally be reserved for more painful presentations or acute exacerbations.

A short period in a walking boot or supportive brace can reduce symptoms and allow tendon irritability to settle. This should be followed by a structured rehabilitation programme rather than prolonged immobilisation. Exercise commonly includes progressive tibialis posterior and calf strengthening, eccentric or heavy-slow resistance loading, intrinsic foot exercises, balance training and proximal hip strengthening. Calf stretching may be appropriate when restricted dorsiflexion contributes to compensatory pronation.

Evidence supports combining exercise with arch-supporting orthoses, although the overall evidence base remains limited. A systematic review found that strengthening exercises may improve pain and disability, with eccentric exercise potentially offering greater benefit than concentric exercise, orthoses or stretching alone. Another review reported that personalised orthoses providing longitudinal arch support were more effective for pain reduction than flat insoles or standard treatment in early-stage disease. bmjopensem.bmj

Orthotic prescription should be individualised. Options range from foot orthoses with medial arch support and rearfoot control to more controlling ankle-foot orthoses for substantial deformity or tendon weakness. Footwear with a stable heel counter, adequate midfoot support and an appropriate rocker may further reduce symptoms. Clinicians should monitor tolerance carefully, since excessive medial pressure or poorly matched control can provoke discomfort elsewhere.

Weight management, management of diabetes and hypertension, smoking cessation, and treatment of inflammatory disease may improve the broader mechanical and biological environment. Analgesics or anti-inflammatory medication may assist short-term symptom control, but persistent pain should not be managed solely with medication.

Surgical management and prognosis

Surgery is considered when appropriately delivered conservative care fails, symptoms remain functionally limiting, or deformity progresses. The procedure depends on the patient’s age, activity requirements, tendon quality, joint degeneration, deformity pattern and flexibility.

Flexible deformity may be treated with combinations of tendon reconstruction, commonly involving flexor digitorum longus transfer, spring-ligament reconstruction, gastrocnemius recession or Achilles-tendon lengthening, and corrective osteotomy such as medialising calcaneal osteotomy. Medial-column procedures may be added when instability or forefoot varus is significant. Rigid deformity or established arthritis is more likely to require joint fusion procedures. If the deltoid ligament and ankle are involved, additional reconstruction or realignment may be necessary.

Outcomes are generally more favourable when the condition is recognised before fixed deformity and degenerative joint changes develop. Rehabilitation after surgery is prolonged and often involves an initial period of protection, followed by progressive weight bearing, range-of-motion work, strengthening and gait retraining.

Posterior tibial tendon dysfunction is best understood as a continuum of tendon insufficiency and progressive foot collapse. Assessment should include tendon symptoms, foot and ankle alignment, deformity flexibility, strength, gait and associated ligament or joint involvement. Early management combines load modification, appropriately prescribed orthoses, supportive footwear and progressive rehabilitation. When deformity becomes fixed or symptoms persist despite conservative care, reconstructive or fusion surgery may be indicated. The modern PCFD classification reinforces the importance of treating the complete mechanical problem rather than focusing exclusively on the tibialis posterior tendon.

Plantar plate tears are an important but often under-recognized cause of forefoot pain, most commonly affecting the lesser metatarsophalangeal joints and especially the second toe. They can produce pain beneath the metatarsal head, swelling, toe drift, and progressive instability that may mimic or lead to a crossover toe deformity.

Anatomy and function

The plantar plate is a strong fibrocartilaginous structure on the plantar side of the metatarsophalangeal joint that helps stabilize the toe during gait and protects the joint surfaces. In the lesser toes, it works with the collateral ligaments, capsule, flexor tendons, and intrinsic muscles to resist excessive dorsiflexion and prevent sagittal and transverse plane instability. When the plate fails, the joint loses a major passive stabilizer, and abnormal toe alignment can develop over time.

How tears develop

Plantar plate tears may occur after acute trauma, but many are degenerative and accumulate gradually under repetitive load. The second MTP joint is most frequently affected because it bears high mechanical stress during propulsion and is often subjected to long second metatarsals, hallux valgus, or overload patterns that increase strain on the plantar structures. As the pathology progresses, attenuation of the plate can lead from pain alone to instability, subluxation, and eventually deformity.

Clinical presentation

Patients usually report pain in the ball of the foot, often localized beneath a specific metatarsal head. Swelling, a feeling that the toe is “coming up” or shifting, and pain on push-off are common, and some patients notice a widening between toes or crossover of the affected digit. In more advanced cases, a hammer toe or clawing posture may appear as the toe loses plantar support. Because the symptoms can resemble metatarsalgia, neuroma, or MTP synovitis, plantar plate injury is frequently missed early. Some people describe a feeling of the sock bunched up under the foot.

Diagnosis

Diagnosis begins with careful history and physical examination, because clinical suspicion is often the key to identifying the problem. Examination may reveal tenderness at the plantar MTP joint, dorsal subluxation, loss of toe purchase, and pain with drawer testing or toe instability maneuvers. Weight-bearing radiographs can show toe deviation, MTP incongruity, arthritis, and metatarsal parabola abnormalities, while MRI and ultrasound can help confirm the tear and define its extent. Early diagnosis matters because deformity and instability become harder to reverse once chronic attenuation has occurred.

Non-operative care

Initial treatment is usually conservative and aims to reduce pain, stabilize the joint, and limit further progression. Common measures include activity modification, footwear with a deep toe box, metatarsal offloading, taping or splinting of the toe into a slightly plantar-flexed position, and orthoses designed to reduce pressure beneath the involved metatarsal head. Symptom relief may occur even if the tear itself does not fully heal, especially when degeneration is advanced. In practice, conservative management is most useful for early or partial injuries and for patients whose symptoms are controllable without major deformity.

Surgical management

Surgery is considered when pain persists, instability progresses, or deformity becomes functionally significant despite conservative care. Procedures may include a metatarsal shortening osteotomy to offload the joint, direct plantar plate repair, or both, and fixed hammertoe deformity may require additional corrective procedures. Surgical planning depends on the degree of instability, the presence of associated deformity, and whether the tear is isolated or part of a broader forefoot overload pattern. Outcomes are generally aimed at restoring alignment, relieving pain, and preventing progression rather than simply “healing” the tissue in isolation.

Prognosis and clinical importance

The overall prognosis depends on the chronicity of the tear, the amount of instability, and how early the condition is recognized. Mild injuries can improve substantially with offloading and stabilization, but longstanding tears often lead to persistent deformity and may require operative correction. For clinicians, the main challenge is to distinguish plantar plate pathology from other causes of forefoot pain before the joint becomes irreversibly unstable. For patients, the key message is that ongoing pain under the forefoot, especially with toe drift or loss of toe purchase, should not be dismissed as simple metatarsalgia.

A concise way to think about it is that the plantar plate is the forefoot’s “check-rein” against toe instability: once it weakens, pressure shifts, the toe can drift, and the problem tends to become progressively more structural.

Plantar fasciitis is best managed with a staged, largely conservative approach that addresses mechanical overload of the plantar fascia, modulates pain, and restores function over time. Most patients improve within 3–6 months with structured nonoperative care, and only a minority require advanced interventions such as injections or surgery.

Pathophysiological basis and principles

Although traditionally labelled an “itis,” plantar fasciitis is now recognised as a degenerative enthesopathy rather than a purely inflammatory process, characterised by micro‑tearing and fibroblast proliferation at the medial calcaneal origin. Repetitive tensile loading from prolonged standing, running, pes planus or cavus, tight gastrocnemius–soleus complex, and suboptimal footwear contribute to overload and impaired tissue healing. Treatment therefore centres on reducing pathological load, optimising the biomechanical environment, and promoting gradual collagen remodelling rather than simply suppressing inflammation.

First‑line conservative management

Initial management is patient‑directed and focuses on relative rest, simple analgesia, and stretching. Activity modification includes reducing or temporarily stopping aggravating activities such as running or long periods of standing, and substituting with low‑impact exercise like cycling or swimming. Ice massage to the plantar heel, short courses of oral or topical NSAIDs, and occasional use of acetaminophen can help control pain sufficiently to allow participation in rehabilitation exercises

Stretching is the cornerstone of early treatment, particularly home‑based plantar fascia and gastrocnemius stretches performed several times daily. Randomised evidence shows that specific plantar fascia stretches yield substantial reductions in pain over the first 6–8 weeks and are superior to some supervised physical therapy regimens alone. Deep friction massage to the plantar fascia and calf, often taught by a physical therapist, can complement stretching by improving local circulation and reducing myofascial restriction.

Footwear, orthotics, and taping

Modifying footwear and providing mechanical support to the arch and heel are key elements of conservative care. Patients are advised to avoid worn, unsupportive shoes and to use footwear with adequate midsole cushioning, heel height, and rearfoot stability. Prefabricated silicone heel cups, gel cushions, or arch supports can reduce peak plantar loading and are supported by evidence as effective adjuncts when combined with stretching.

Functional foot orthoses, whether prefabricated or custom devices, are widely used to control excessive pronation, redistribute pressure, and reduce strain on the plantar fascia. Clinical guidelines recommend their use in patients whose symptoms persist after basic measures, with many studies reporting improved pain and function over 6–12 weeks. Low‑Dye and other taping techniques can provide short‑term relief by temporarily supporting the medial arch and unloading the plantar fascia, and are particularly useful in acute presentations or to “test” orthotic concepts before prescription.

Night splints, which hold the ankle in dorsiflexion and prevent the plantar fascia from shortening overnight, can reduce the characteristic first‑step pain and are effective in chronic cases when used for several weeks. Their benefit appears greatest in patients who present with severe morning symptoms and who have coexisting gastrocnemius tightness.

Physical therapy and intermediate modalities

For patients who do not respond adequately to first‑line measures over 6–8 weeks, formal physical therapy can add structured stretching, strengthening, and adjunctive modalities. Therapists often employ gastrocnemius–soleus and plantar fascia stretches, eccentric calf strengthening, proprioceptive training, and soft tissue techniques to optimise lower limb mechanics. Cryotherapy, iontophoresis with corticosteroids or acetic acid, and ultrasound or laser‑based treatments may be incorporated to reduce pain and facilitate exercise participation.

Recent evidence supports photobiomodulation therapy (PBMT), including low‑level laser therapy, as an intermediate option for persistent plantar fasciitis, with meta‑analyses showing significant short‑term pain reduction and improved outcomes when combined with exercise. Extracorporeal shock wave therapy (ESWT), in radial or focused forms, has also become an important noninvasive modality for chronic cases, producing faster pain relief than some alternatives and contributing to reductions in fascia thickness on imaging. These therapies are typically considered after 8–20 weeks of unsuccessful standard conservative care.

Injection therapies and minimally invasive options

When symptoms remain disabling beyond 3–6 months despite comprehensive conservative management, injectable and minimally invasive procedures may be appropriate. Corticosteroid injections have long been used and can provide short‑term pain relief, but carry recognised risks including plantar fascia rupture and fat pad atrophy; thus most guidelines recommend judicious use and avoidance of repeated injections. Dry needling (percutaneous fenestration) of the fascia, even without drug delivery, has shown pain reduction within weeks by stimulating a local healing response

Regenerative approaches such as platelet‑rich plasma (PRP), autologous blood injections, hypertonic dextrose prolotherapy, and newer agents like polydeoxyribonucleotide or calcium phosphate aim to enhance fibroblast activity and collagen deposition. Systematic reviews indicate that PRP often yields superior medium‑term pain relief and functional improvement compared with corticosteroid injection or ESWT in chronic plantar fasciitis. Prolotherapy with dextrose has demonstrated short‑ and long‑term improvements comparable to radial ESWT when administered in serial ultrasound‑guided injections. Botulinum toxin injections into the calf musculature may reduce tension transmitted to the fascia and have emerging evidence in selected chronic patients.

Surgical intervention and prognosis

Surgery is reserved as a last resort for recalcitrant plantar fasciitis that persists beyond 12 months despite exhaustive conservative, physical therapy, and injection‑based treatments. Endoscopic or open partial plantar fasciotomy, sometimes combined with gastrocnemius recession, aims to release the overloaded portion of the fascia and rebalance force distribution through the foot. Contemporary evidence suggests endoscopic plantar fascia release offers substantial improvement in pain and AOFAS scores with lower complication rates than open procedures, though risks such as lateral column pain, nerve injury, and arch destabilisation remain.

Overall, plantar fasciitis is a self‑limiting condition in most individuals, with more than 90% achieving symptomatic relief through conservative treatment within 3–6 months. The best outcomes occur when therapy is initiated early and tailored to individual biomechanical risk factors, combining education, stretching, load management, mechanical support, and, when needed, intermediate modalities or regenerative injections. For clinicians, a phased, evidence‑based framework—from initial home care through orthoses and physical therapy, then selective advanced therapies, and finally surgery—provides a clear structure for guiding patients from acute heel pain back to full function.

Pes cavus, commonly called a high-arched or “claw” foot, is a structured deformity in which the longitudinal arch of the foot is abnormally elevated, producing a relatively stiff foot with increased pressure under the heel and forefoot. Although it can be an isolated, idiopathic variant, pes cavus is often a clinical sign of underlying neuromuscular disease, and its management must therefore address both the foot morphology and the causative pathology.

Definition and Classification

Pes cavus is defined as an exaggerated elevation of the medial longitudinal arch, visible in the sagittal plane, and is often accompanied by associated deformities such as hindfoot varus, forefoot adduction, and plantar flexion of the first ray. The terms “pes cavus” and “pes cavovarus” are frequently used interchangeably, though cavovarus implies a triplane deformity with varus of the hindfoot and adduction of the forefoot superimposed on the cavus component.

Three main subtypes are commonly described: anterior cavus, posterior cavus, and mixed cavus. Anterior cavus is associated with a plantar-flexed first ray and forefoot pronation, while posterior cavus is dominated by a calcaneal pitch increase and hindfoot varus; mixed cavus combines features of both. In clinical practice, the distinction is important because it guides both biomechanical assessment and surgical planning.

Epidemiology and Aetiology

In adults, the prevalence of pes cavus is estimated at approximately 10–29%, with no clear gender predominance. Many cases are idiopathic or familial, but a significant proportion are acquired and linked to neurological or musculoskeletal conditions.

Neurological aetiologies include:

• Hereditary motor and sensory neuropathies, particularly Charcot–Marie–Tooth disease
• Spinal cord disorders such as spinal dysraphism, tumors, or trauma
• Upper motor neuron conditions like cerebral palsy or stroke
• Peripheral nerve lesions, for example from compartment syndrome or trauma

Non-neurological causes include congenital deformities (e.g., clubfoot residual deformity), trauma with malunion, inflammatory conditions, and muscle imbalances secondary to local pathology. Importantly, the presence of a rigid, progressively worsening cavus foot in a child or young adult should prompt investigation for an underlying neuromuscular disorder.

Clinical Features and Symptoms

Patients with pes cavus typically present with:

• Pain localized to the heel, lateral forefoot, and sometimes the arch, due to focal overload
• Recurrent ankle sprains and a sense of instability, as the high arch reduces the contact area and compromises shock absorption
• Clawing or hammertoes, caused by imbalance between intrinsic and extrinsic muscles of the foot
• Difficulty with footwear, as the high arch and rigid foot shape can create pressure points and poor fit.

Gait abnormalities may include a shortened stance phase, increased lateral loading, and a tendency to “stiff-knee” gait in more severe neuromuscular cases. In children, parents may note that the child walks on the outer border of the foot or has frequent “falling over” of the ankle.

Assessment and Diagnosis

A comprehensive assessment begins with a detailed history, including family history of neuropathy, developmental milestones, and progression of the deformity. Neurological examination should evaluate distal muscle strength, tone, reflexes, and sensory function, as subtle signs of neuropathy may be present even when the foot deformity is the most obvious feature

Physical examination focuses on:

• Arch height and flexibility: a rigid cavus suggests a more established or neuromuscular cause
• Hindfoot position: varus is common and may be fixed or reducible
• Forefoot alignment: adduction and pronation are frequent
• Toe posture: claw toes indicate intrinsic weakness or imbalance
• Muscle bulk and tendon tightness, particularly the Achilles and plantar fascia.[acnr.co]

Radiographic evaluation includes weight-bearing foot X-rays to measure calcaneal pitch, first-ray angle, and other indices of arch elevation and hindfoot/forefoot alignment. In suspected neuromuscular cases, further investigations such as electromyography (EMG), nerve conduction studies, or genetic testing may be warranted to identify the underlying condition

Management Principles

Management of pes cavus is guided by the severity of the deformity, the presence of symptoms, the flexibility of the foot, and the underlying aetiology. The overarching goals are to reduce pain, improve function and stability, prevent progression, and, where possible, address the causative condition.

Conservative Management

Conservative measures are the first line of treatment for mild to moderate, flexible deformities:

• Orthotic devices: Custom foot orthoses with appropriate arch support, heel cupping, and forefoot relief can redistribute pressure, improve stability, and reduce pain. In neuromuscular cases, orthoses may also need to accommodate claw toes or varus alignment.[
• Footwear modification: Shoes with a supportive midsole, adequate cushioning, and a wide toe box help accommodate the high arch and clawed toes while reducing lateral overload.
• Physical therapy: Targeted stretching of the Achilles tendon and plantar fascia, alongside strengthening of intrinsic foot muscles and hip stabilizers, can improve flexibility and dynamic control. Gait retraining may be beneficial in cases with significant instability.

Conservative management is often insufficient for rigid, severe deformities or when there is progressive neurological deterioration, but it remains central in the long-term management of many patients.

Surgical Management

Surgery is indicated when conservative measures fail, when the deformity is markedly rigid, or when there is significant functional impairment or recurrent injury. The choice of procedure depends on the subtype of cavus, the site of the deformity, and the underlying pathology.

Common surgical options include:

• Soft-tissue procedures: Tendon transfers (e.g., flexor digitorum longus to first metatarsal) and lengthening of tight structures (Achilles, plantar fascia) to correct muscle imbalance and improve alignment.
• Osteotomies: Calcaneal osteotomies to reduce hindfoot varus; first-ray elevating osteotomies to correct plantar flexion of the first metatarsal; and midfoot or forefoot osteotomies to address adduction and arch elevation.
• Arthrodesis: In severe, rigid deformities, especially in the context of neuromuscular disease, fusion of selected joints (e.g., subtalar or triple arthrodesis) may be necessary to achieve a stable, plantigrade foot.

Surgical planning must be carefully integrated with the management of the underlying neuromuscular condition, as recurrence or progression may occur if the primary disease is not addressed.

Pes cavus is not merely a structural variant of the foot but a potentially significant clinical sign that warrants thorough evaluation for underlying neuromuscular pathology. Its management requires a nuanced combination of biomechanical understanding, neurological assessment, and tailored treatment ranging from orthotics and physical therapy to complex reconstructive surgery. For podiatrists and allied professionals, recognizing the patterns of cavus deformity, understanding its subtypes, and integrating conservative and surgical options within a broader diagnostic framework are essential to optimising outcomes for patients with this challenging condition.

Peroneal tendonitis is a common yet often under-recognized cause of lateral ankle pain, particularly in athletic populations and individuals with biomechanical abnormalities of the foot and ankle. The condition involves inflammation or degeneration of the peroneal tendons—specifically the peroneus longus and peroneus brevis—as they course posterior to the lateral malleolus and insert into the foot. Given their essential role in dynamic ankle stability and foot function, pathology affecting these tendons can significantly impair gait and athletic performance.

The peroneal tendons originate from the lateral compartment of the leg. The peroneus longus arises from the proximal fibula and lateral tibial condyle, while the peroneus brevis originates more distally from the fibular shaft. Both tendons pass through the retrofibular groove, secured by the superior peroneal retinaculum, before diverging distally. The peroneus brevis inserts onto the tuberosity of the fifth metatarsal, whereas the peroneus longus courses plantarward across the cuboid and inserts at the base of the first metatarsal and medial cuneiform. Functionally, these tendons act to evert the foot and contribute to plantarflexion, while also providing lateral ankle stability, particularly during the stance phase of gait.

Peroneal tendonitis typically arises from repetitive overuse, resulting in microtrauma and subsequent inflammation or tendinopathy. It is frequently observed in runners, especially those who train on uneven surfaces or perform excessive hill running. Sudden increases in training intensity, duration, or frequency are well-established risk factors. Biomechanical contributors play a significant role; individuals with cavovarus foot alignment are particularly predisposed due to increased lateral column loading and chronic tensile stress on the peroneal tendons. Additionally, lateral ankle instability following previous sprains can lead to compensatory overactivation of the peroneal muscles, further exacerbating tendon overload.

Clinically, patients with peroneal tendonitis present with lateral ankle pain that may radiate distally along the course of the tendons. Pain is typically exacerbated by activity, particularly during resisted eversion or passive inversion of the foot. Swelling and tenderness posterior to the lateral malleolus are common findings, and in some cases, crepitus may be appreciated, suggesting tenosynovitis. Chronic cases may demonstrate tendon thickening or weakness in eversion strength. It is important to differentiate peroneal tendonitis from other causes of lateral ankle pain, such as lateral ligament sprains, sinus tarsi syndrome, or fractures of the fifth metatarsal.

Diagnostic evaluation is primarily clinical but may be supplemented by imaging in ambiguous or refractory cases. Ultrasound provides a dynamic, cost-effective modality for assessing tendon integrity, detecting tenosynovitis, and identifying subluxation. Magnetic resonance imaging (MRI) offers superior soft tissue contrast and is particularly useful in evaluating tendon tears, degenerative changes, or associated pathology such as retinacular injury. Imaging is especially indicated when symptoms persist despite conservative management or when surgical intervention is being considered.

Management of peroneal tendonitis is predominantly conservative and focuses on reducing inflammation, correcting biomechanical contributors, and gradually restoring function. Initial treatment typically includes activity modification, rest, and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) where appropriate. Cryotherapy and compression may help manage acute inflammation. Immobilization in a walking boot may be indicated in more severe cases to allow tendon healing.

A key component of treatment involves addressing underlying biomechanical abnormalities. Foot orthoses can be particularly beneficial, especially in patients with cavus or varus alignment. Devices designed to increase lateral forefoot support and reduce excessive supination can offload the peroneal tendons. Lateral wedging or modifications to improve pronatory moments may be considered, depending on the individual’s gait pattern. Footwear modifications, including the use of stable, cushioned shoes with adequate lateral support, are also important in mitigating excessive tendon stress.

Rehabilitation plays a critical role in recovery and prevention of recurrence. Physiotherapy programs typically focus on progressive strengthening of the peroneal muscles, proprioceptive training, and correction of movement patterns. Eccentric loading exercises have shown efficacy in the management of tendinopathies and may be incorporated into rehabilitation protocols. Additionally, addressing proximal kinetic chain deficits, such as hip abductor weakness or poor neuromuscular control, can reduce compensatory loading at the ankle.

In cases where conservative treatment fails, or when structural abnormalities such as tendon tears or subluxation are present, surgical intervention may be warranted. Procedures may include tendon debridement, repair of longitudinal splits, or reconstruction of the superior peroneal retinaculum. Postoperative rehabilitation is essential to restore strength and function, with gradual return to activity over several months.

Prevention of peroneal tendonitis centers on appropriate training practices, biomechanical optimization, and early intervention. Gradual progression of training loads, adequate recovery periods, and cross-training can help minimize overuse injuries. Screening for and addressing biomechanical risk factors, particularly in high-risk populations such as runners, is essential. Education on proper footwear selection and terrain considerations can further reduce the risk of tendon overload.

Peroneal tendonitis is a multifactorial condition that reflects the interplay between mechanical loading, anatomical predisposition, and activity demands. A thorough understanding of the underlying biomechanics and risk factors is essential for accurate diagnosis and effective management. With appropriate conservative care, most patients achieve favorable outcomes; however, recognition of refractory cases and timely referral for advanced imaging or surgical consultation is critical. For clinicians, particularly those involved in sports medicine and podiatry, a comprehensive and individualized approach remains the cornerstone of successful treatment and long-term prevention.

Peroneal spastic flatfoot (PSFF) is a rigid, painful valgus deformity of the foot historically associated with protective spasm of the peroneal muscles, now recognized as a clinical syndrome rather than a single disease entity. While often linked to tarsal coalition, it can also occur in the absence of developmental anomalies, and in many cases the “spasm” is more accurately an adaptive shortening or reactive contraction secondary to an irritative lesion in the peritalar region. Because of its variable etiology and outdated terminology, modern podiatric and orthopedic literature frequently uses broader terms such as “rigid valgus foot” or specifies the underlying pathology (e.g., calcaneonavicular bar, talocalcaneal bridge, inflammatory arthritis)

Definition and Terminology

Peroneal spastic flatfoot describes a foot in which the arch is flattened, the heel is in valgus, and the foot is stiff or rigid, with apparent spasm of the peroneal muscles causing pain and limiting motion. Classic descriptions emphasize unilateral or bilateral rigid flatfoot with peroneal muscle tenderness and a foot that resists manual correction into inversion or neutral.

The term is now considered imprecise by many authors. In cases where tarsal coalition is present, the deformity is primarily a fixed structural problem due to abnormal bone union; the peroneal “spasm” is then an adaptive shortening rather than true primary spasm. In inflammatory cases (e.g., rheumatoid arthritis), peroneal spasm may be more genuine, but these are better classified separately as arthritic flatfoot with peroneal spasm. Consequently, contemporary texts often prefer “rigid flatfoot due to [specific coalition]” or reserve PSFF for idiopathic presentations where no coalition or other cause is identified.

Etiology

The most common cause of PSFF is tarsal coalition, particularly calcaneonavicular bars and talocalcaneal bridges. These congenital or developmental unions between tarsal bones restrict motion at the subtalar and peritalar joints, producing a rigid valgus deformity and peroneal irritation. Radiographs with special oblique views are often required to detect rudimentary forms of these coalitions.

However, PSFF can occur without detectable tarsal anomalies. Historical series have documented cases with normal tarsal skeletons in which peroneal spasm was clinically evident, suggesting that any irritative lesion in the peritalar region—such as trauma, sinus tarsi pathology, neoplasm, or inflammatory disease—can provoke protective peroneal contraction and a rigid flatfoot posture. Idiopathic peroneal spastic flatfoot (IPSF) is used when no cause is found after thorough clinical, laboratory, and imaging evaluation.

Less common etiologies include inflammatory arthropathies (notably rheumatoid arthritis), where true peroneal spasm may accompany joint destruction, and rare neoplasms manifesting as a rigid flatfoot deformity. Heavy mechanical stress on an architecturally abnormal or even normal foot is also hypothesized to contribute, with tarsal anomalies increasing susceptibility to breakdown under average stress.

Clinical Features

Patients typically present in childhood or adolescence with a painful, stiff foot that is flat and in valgus. The deformity is often unilateral but can be bilateral. The foot is rigid: inversion and abduction are limited, and the foot cannot be passively corrected into a neutral or varus position. Peroneal tenderness along the lateral foot and behind the lateral malleolus is characteristic, and patients may report pain in the sinus tarsi or lateral aspect of the foot

Gait may show an antalgic pattern, with avoidance of pronation and altered weight distribution. There may be a history of recurrent ankle sprains or minor trauma, but in some cases the onset appears spontaneous. In older children and adolescents, the deformity may be more established, with secondary changes in the soft tissues and alignment of the lower limb.

Diagnosis

Diagnosis relies on clinical examination, plain radiography, and advanced imaging. Clinical assessment confirms a rigid valgus flatfoot with peroneal tenderness and limited subtalar motion. Standard weight-bearing radiographs show a flattened longitudinal arch, valgus tilt of the calcaneus, and possible uncovering of the talonavicular joint

Specialized radiographic views (e.g., oblique calcaneonavicular views, lateral talar–calcaneal angle) are essential to detect calcaneonavicular bars and talocalcaneal bridges, which may be missed on routine films. CT is now the gold standard for defining the morphology and extent of tarsal coalitions, while MRI is valuable for evaluating soft tissue irritation, sinus tarsi pathology, and inflammatory or neoplastic processes. In cases where no coalition is identified, the diagnosis of IPSF is considered, and further investigation for inflammatory, neurologic, or neoplastic causes is warranted.

Management

Conservative management is the initial approach, particularly in children and those with mild symptoms. This includes activity modification, avoidance of high-impact loading, and use of immobilization or short-term casting in severe, refractory cases to reduce peroneal irritation and restore some flexibility. Orthotic devices designed to support the medial arch, control valgus, and offload the peroneal tendons are commonly used, along with physical therapy to improve peroneal and intrinsics strength and flexibility.

Surgical intervention is indicated when there is persistent pain, functional limitation, or progressive deformity despite conservative measures. For coalitions, the standard procedure is resection of the bar with interposition of fat, tendon, or other material to prevent recurrence and restore motion. In idiopathic cases or when resection is not feasible, procedures such as peroneal tendon lengthening, medial soft-tissue releases, or corrective osteotomies (e.g., calcaneal osteotomy, triple arthrodesis) may be required, depending on the degree of rigidity and deformity. The choice of procedure is guided by the underlying etiology, age, and functional demands of the patient.

Peroneal spastic flatfoot is best understood as a heterogeneous clinical syndrome characterized by rigid valgus flatfoot with peroneal irritation, rather than a single pathologic entity. While tarsal coalition is the predominant cause, idiopathic and inflammatory forms exist, and the term “spastic” is often misleading. Accurate diagnosis requires careful imaging to identify or exclude coalitions and other structural abnormalities, and management should be tailored to etiology, with conservative measures first and surgery reserved for refractory or advanced cases.

Heel pain is most commonly caused by overload or inflammation of the plantar fascia or Achilles tendon, but it can also arise from bony, neural, and systemic disorders. Because the heel tolerates significant ground reaction forces during weight-bearing, even subtle biomechanical or tissue changes can produce disabling symptoms. This essay outlines the principal causes of heel pain, grouped by anatomical region and mechanism, with reference to underlying pathophysiology and clinical context.

Plantar (inferior) heel pain

Plantar fasciitis

Plantar fasciitis is the single most common cause of heel pain. The plantar fascia is a thick aponeurosis that extends from the medial calcaneal tuberosity to the bases of the toes, acting as a dynamic stabiliser of the foot arch. Repetitive tensile loading—particularly with excessive pronation, tight calf muscles, or sudden increases in activity—produces microtrauma and degenerative changes at the fascial origin rather than purely inflammatory ones. Clinically, this manifests as sharp, focal pain at the medial inferior heel, often worst with the first steps after rest and improved with mild activity, then returning after prolonged standing.

Risk factors include obesity, flat feet or rigid high arches, abnormal gait (e.g. overpronation), prolonged standing on hard surfaces, and wearing shoes with poor cushioning or support. In chronic cases, traction at the calcaneal attachment may stimulate a plantar heel spur; the spur itself is often not painful, but reflects the same biomechanical overload that drives fasciitis.

Heel spur and fat pad atrophy

Heel spurs are bony projections that can develop on the inferior calcaneus in association with chronic plantar fasciitis or traction. While many patients with spurs are asymptomatic, some experience localized inferior heel pain, especially during weight-bearing after rest. Fat pad atrophy refers to thinning of the subcutaneous cushion beneath the calcaneus, commonly seen in older adults or after repeated steroid injections. Loss of this natural padding reduces shock absorption, producing deep, central heel pain that worsens with barefoot walking and improves when the patient walks on their toes, thereby shifting load away from the central heel.

Calcaneal stress fracture and bruising

Calcaneal stress fractures result from repetitive overload, often in runners, military personnel, or individuals who suddenly increase activity on hard surfaces. Pain is typically diffuse over the heel, present with weight-bearing, and may not improve with rest; compression of the calcaneus from side to side often reproduces pain. Early radiographs can be normal, necessitating MRI or bone scan for diagnosis. Acute heel bruise (contusion) occurs after a direct impact, such as landing from a jump or stepping on a hard object, causing localized pain and sometimes swelling.

Posterior (back of heel) pain

Achilles tendinitis and tendinopathy

Achilles tendinitis (more accurately, tendinopathy) is a common cause of posterior heel pain, affecting the tendon that connects the calf muscles to the calcaneus. Repetitive microtrauma from running, jumping, or abrupt increases in training load leads to degeneration and failed healing within the tendon, often with associated swelling and pain 2–6 cm above the calcaneal insertion. Pain is typically worse at the start of activity, may ease with warming up, and then recur after prolonged use. Risk factors include tight gastrocnemius–soleus muscles, poor footwear, and biomechanical abnormalities such as excessive pronation or hindfoot varus.

Retrocalcaneal bursitis and Haglund’s deformity

Retrocalcaneal bursitis involves inflammation of the bursa between the Achilles tendon and the anterior surface of the calcaneus, producing pain and swelling at the back of the heel, often with redness. It is frequently associated with Haglund’s deformity, a bony prominence on the posterosuperior calcaneus that impinges on surrounding soft tissues during ankle motion. The combination of bony enlargement and repetitive friction can cause significant pain, especially in active individuals or those wearing rigid-backed shoes.

Achilles tendon rupture

A complete or partial rupture of the Achilles tendon typically occurs after a sudden, forceful push-off or landing, often with a audible “pop” and immediate inability to calf-rise or walk normally. Pain may be severe initially but can become less intense as the tendon heals in a non-functional position, leading to persistent weakness and gait abnormality.

Medial, lateral, and neural causes

Tarsal tunnel syndrome and nerve compression

Tarsal tunnel syndrome results from compression of the posterior tibial nerve as it passes through the tarsal tunnel on the medial aspect of the foot, producing burning pain, tingling, or numbness in the heel and arch. Tenderness over the tunnel and a positive Tinel’s sign support the diagnosis. Baxter’s nerve compression, involving the first branch of the lateral plantar nerve, can mimic plantar fasciitis with medial plantar heel pain and is often under-recognized in runners. Peripheral neuropathy, particularly in diabetes, can also produce diffuse or burning heel pain, often with altered sensation and decreased protective reflexes.

Referred pain from lumbar radiculopa
