Sever's Disease

Lower Limb

Overview

Sever's disease is an inflammatory condition of the calcaneal apophysis, the growth plate of the heel bone in children and adolescents. It is the most common cause of heel pain in the pediatric population, typically occurring during growth spurts in active children aged 8-14 years. The condition results from repetitive microtrauma and traction forces at the insertion of the Achilles tendon on the developing heel.

Pathophysiology

Sever's disease develops when repetitive traction forces from the Achilles tendon and plantar fascia exceed the tolerance of the immature calcaneal apophysis. During periods of rapid skeletal growth, the apophysis is a relatively weak area of the bone, vulnerable to traction and shear stresses. Chronic microtrauma causes inflammation and degenerative changes at the growth plate, resulting in pain at the insertion site. The condition typically resolves once skeletal maturity is achieved and growth plates close.

Typical Presentation

Site

Posterior and plantar heel pain at the insertion of the Achilles tendon; frequently bilateral

Quality

Aching, throbbing, or sharp pain; worse with activity and at night

Intensity

Mild to moderate pain (4-6/10), typically activity-dependent; can become severe (8-9/10) if activity is not modified

Aggravating

High-impact activities (running, jumping, sports), prolonged walking, tight footwear, hard surfaces, rapid growth periods, excessive calf muscle tension

Relieving

Rest, ice application, anti-inflammatory measures, activity modification, heel cups or cushioning, calf muscle stretching and relaxation

Associated

Limping gait, reluctance to participate in sports, tight calf muscles on examination, tenderness at Achilles insertion on calcaneus, mild swelling around heel, toe-walking to avoid heel pain, symptoms often worse at end of sports season

Orthopaedic Tests

Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.

Further reading: full test procedures are described in standard clinical examination texts, e.g. Magee & Manske, Orthopedic Physical Assessment (7th ed.), and Cook & Hegedus, Orthopedic Physical Examination Tests: An Evidence-Based Approach (2nd ed.).

No accuracy study

Calcaneal Compression Test (Squeeze Test)

Procedure

Squeeze the back of the heel from both sides with the palms of your hands or thumb and fingers.

Positive Finding

Pain at the back of the heel with side-to-side compression.

Interpretation

Supports Sever's disease (calcaneal apophysitis) in an active child or young adolescent whose growth plates are still open. Pain at rest or at night, a limp without activity, swelling or fever needs medical assessment.

Sources

Performance measure

Single-Leg Stance or Single-Leg Hop Test

Procedure

Ask the child to stand on the affected leg, rise onto the toes, then hop gently.

Positive Finding

Heel pain with standing on tiptoe or hopping.

Interpretation

Shows load tolerance and helps guide activity modification. Not a diagnostic test.

Sources

No accuracy study

Dorsiflexion Range of Motion Assessment

Procedure

Patient supine or seated. Examiner passively dorsiflexes the ankle and foot, noting range and any pain response.

Positive Finding

Reduced ankle dorsiflexion relative to the contralateral side, or reproduction of heel pain during stretch

Interpretation

Tight gastrocnemius–soleus complex is a common biomechanical contributor to Sever's disease. Reduced dorsiflexion suggests plantarflexor tightness, which increases apophyseal stress during gait and running.

Sources

No accuracy study

Palpation of Calcaneal Apophysis

Procedure

Palpate the back and the underside of the heel, at the growth plate where the Achilles tendon and plantar fascia attach.

Positive Finding

Tenderness at the back or underside of the heel bone.

Interpretation

Supports Sever's disease. Diagnosis is usually clinical; X-rays are not routinely needed but should be arranged if pain is on one side only and persistent, or if there are red flags.

Sources

Not a diagnostic test

Silfverskiöld Test

Procedure

Child supine. Hold the heel in neutral and dorsiflex the ankle with the knee straight, then bent to 90°. Compare with the other side.

Positive Finding

Dorsiflexion limited with the knee straight and better with it bent (gastrocnemius tightness).

Interpretation

Calf tightness is common during growth spurts and increases pull on the heel growth plate. A treatment target (stretching, heel raise), not a diagnostic test.

⚠ Red Flags

  • •Severe pain disproportionate to clinical findings suggesting fracture or other serious pathology
  • •Systemic signs of infection (fever, spreading swelling, erythema)
  • •Neurological symptoms (numbness, tingling, weakness) suggesting nerve compression
  • •Signs of septic arthritis or osteomyelitis (severe swelling, inability to bear weight, systemic illness)
  • •Unilateral presentation with redness and warmth suggesting alternative diagnosis
  • •Pain persisting beyond expected resolution timeframe without improvement with conservative management

⚡ Yellow Flags

  • •Excessive parental pressure to return to sport before symptoms resolve
  • •Perfectionist personality traits in young athlete
  • •Anxiety about missing sports participation or competitive events
  • •Social withdrawal related to activity restriction
  • •Catastrophizing about heel pain or pain chronicity
  • •Poor compliance with activity modification recommendations
  • •Family history of chronic pain conditions

Osteopathic Techniques

Sever disease settles once the heel growth plate closes, and surgery is not needed. Care is limiting painful running and jumping, ice, and heel lifts or cups; calf stretches can ease the pull of the Achilles. In a randomised trial, wait-and-see, a heel raise and physical therapy all reduced heel pain, with no clinically relevant difference between them at the end.

Region

Calf (gastrocnemius and soleus)

Technique

Muscle energy, calf (gastrocnemius and soleus)
Grade D
Low evidence: expert consensus or could not be verified against literature
No trials of calf MET. Calf stretching is a recommended part of care.

Rationale

Muscle energy technique to lengthen the gastrocnemius and soleus.

How it's done, cautions & evidence

How it's done

The calf is taken to its barrier by dorsiflexing the ankle. The patient pushes the foot gently down, at about 10–20% effort, against resistance for 5–10 seconds, relaxes for 3–5 seconds, and the new barrier is taken up.

Cautions

Not used with an acute fracture, a joint infection or a bone malignancy; take care with severe osteoporosis or after surgery that limits muscle contraction. Use the least force needed: too much can tear a muscle or pull off a tendon, especially in older patients.

Region

Talocrural and subtalar joints

Technique

Articulation, ankle and footNo trials found

Rationale

Gentle glides of the ankle, subtalar and midfoot joints to restore movement.

How it's done, cautions & evidence

How it's done

Passive, rhythmic, low-velocity glides of the ankle (talocrural), subtalar, midfoot and toe joints, within or up to the end of the available range, often aimed at restoring ankle dorsiflexion.

Cautions

Before mobilising an acute ankle injury, check for fracture with the Ottawa ankle rules (tenderness over either malleolus), and palpate the base of the 5th metatarsal, the navicular and the midfoot for a Lisfranc injury.

Evidence in Sever's Disease

Searched 26 Oct 2026: no trials of ankle or foot mobilisation in Sever disease.

Region

Plantar fascia and intrinsic foot muscles

Technique

Counterstrain, foot and ankle tender pointsNo trials found

Rationale

Counterstrain: hold a tender point in a position of ease for about 90 seconds.

How it's done, cautions & evidence

How it's done

Find a tender point in the foot, ankle or calf. Passively move the foot and ankle into the position where the tenderness and tissue tension ease most, and hold it for about 90 seconds while monitoring the point. Return slowly to neutral and re-check.

Cautions

Do not use over an acute fracture, or in a patient who cannot give feedback.
