Sever’s disease (calcaneal apophysis) is the most common cause of heel pain in children aged 8–14 — but the one activity level factor that determines whether it resolves with heel lifts alone or requires 6 weeks in a walking boot is rarely communicated to parents.

Calcaneal apophysitis — better known as Sever’s disease — is the most common cause of heel pain in children and adolescents, affecting active children ages 8-15. It arises from traction stress on the calcaneal apophysis (growth plate) by the Achilles tendon and plantar fascia during a period of rapid bone growth. Despite causing significant activity-limiting pain, it is a self-limiting condition that resolves completely when the apophysis fuses, typically by age 14-16.
Sever’s Disease: Clinical Profile
| Feature | Details |
|---|---|
| Age range | 8-15 years; peak 10-12 in girls, 11-13 in boys |
| Gender | Slightly more common in males; bilateral in 60% |
| Mechanism | Traction apophysitis: Achilles + plantar fascia pull on open growth plate during rapid growth |
| Classic symptom | Posterior-inferior heel pain with activity; worse after rest then re-loading; limp after sports |
| Squeeze test | Medial-lateral compression of calcaneal growth plate reproduces pain (positive in 85%) |
| X-ray findings | Not diagnostic; fragmentation/sclerosis of apophysis is normal variant — do not diagnose from X-ray alone |
| Natural history | Self-limiting; resolves with apophyseal fusion (typically age 14-16) |
Treatment Ladder for Sever’s Disease
| Severity | Intervention | Evidence/Notes |
|---|---|---|
| Mild (plays through discomfort) | Heel cups (silicone) to reduce Achilles traction; calf stretching program; activity modification | Most effective first-line; reduces traction force on apophysis |
| Moderate (limping after sport; limits activity) | Add semi-rigid orthotic; NSAIDs (ibuprofen) for acute flares; reduce high-impact training volume | Orthotics with heel elevation reduce insertional tension |
| Severe (pain at rest; unable to participate) | Short-term immobilization (CAM boot 2-4 weeks); complete activity modification; PT for calf flexibility | Boot breaks acute pain cycle; return to sport gradually after boot |
| Refractory | Refer for imaging to exclude stress fracture, tarsal coalition, or bone tumor; consider MRI | Sever’s is a clinical diagnosis; imaging when presentation atypical |
At Balance Foot & Ankle in Howell and Bloomfield Hills, we evaluate pediatric heel pain with a clinical exam and, when indicated, imaging to confirm the diagnosis and exclude other causes. Most children with Sever’s disease return to full sport within 2-6 weeks of starting appropriate treatment. Call (810) 206-1402.

Doctor Answer
What is calcaneal apophysitis and how is it treated in children?
Calcaneal apophysitis, or Sever’s disease, is the most common cause of heel pain in growing children aged 8-14. It occurs when the Achilles tendon pulls on the growth plate at the back of the heel during rapid growth spurts. Treatment includes heel cushions, calf stretching, activity modification, and temporary avoidance of high-impact sport. Most children recover fully within 2-3 months and the condition resolves permanently once the growth plate closes.
