Calcaneal stress fracture — a fatigue failure of the calcaneus (heel bone) from repetitive loading exceeding bone remodeling capacity — is an underdiagnosed cause of diffuse posterior heel pain in runners, military recruits, and active individuals. Unlike metatarsal stress fractures, calcaneal stress fractures produce a distinctive pain pattern and examination finding that allows clinical diagnosis before imaging confirmation.

Diagnosis

Clinical presentation: diffuse posterior heel pain that worsens progressively with weight-bearing activity over 2–4 weeks — unlike the first-step plantar fasciitis pain, calcaneal stress fracture pain worsens during activity and may persist into rest in advanced cases. The medial-lateral calcaneal squeeze test: direct lateral-to-medial and medial-to-lateral compression of the calcaneal body between the examiner’s hands — significant pain with this test has 80%+ sensitivity for calcaneal stress fracture. Imaging: plain X-rays are insensitive early (periosteal reaction visible at 2–3 weeks); MRI demonstrates bone marrow edema within 24–48 hours of injury and defines the fracture line; bone scan is highly sensitive but less specific. Ultrasound: periosteal elevation and hyperemia at the fracture site are visible on high-frequency ultrasound in experienced hands.

Risk Factors and Return to Activity

Risk factors: female sex (female athlete triad — low energy availability, menstrual dysfunction, low bone mineral density); military training (sudden mileage increase on hard surfaces); osteoporosis or vitamin D deficiency; previous stress fracture (indicates systemic bone metabolism risk); rapid mileage increase in runners (>10% weekly increase). Treatment: reduction in weight-bearing activity (not necessarily complete non-weight-bearing for calcaneal fractures — a boot or rigid shoe with heel cushioning allows protected walking in most cases); calcium and vitamin D optimization; bone density screening for recurrent or atypical presentations. Return to activity: gradual return beginning at 6–8 weeks based on resolution of squeeze test tenderness — full unrestricted running at 10–12 weeks. Dr. Biernacki at Balance Foot & Ankle evaluates suspected calcaneal stress fracture with the calcaneal squeeze test and diagnostic ultrasound or MRI referral for confirmation.

Frequently Asked Questions

How long does a foot stress fracture take to heal?

Most foot stress fractures heal within 6–8 weeks with proper offloading. High-risk fractures (Jones fracture, navicular stress fracture) can take 3–6 months and sometimes require surgery. Premature return to activity is the most common cause of delayed healing.

How do I know if I have a stress fracture?

Stress fractures cause localized pain that worsens with activity and improves with rest, often with point tenderness over a specific bone. X-rays may be negative for 2–3 weeks after onset — MRI provides definitive diagnosis earlier.

Can you walk on a stress fracture?

This depends on the fracture location and severity. Many foot stress fractures allow limited walking in a protective boot. High-risk fractures (Jones, navicular) typically require non-weight-bearing. Walking on an unprotected stress fracture risks complete fracture.
