Stress fractures are the most serious overuse injury in running — and the most important to manage correctly. Return too soon and you risk a complete fracture. Managed well, most athletes return to full training within 3–5 months stronger and better equipped to prevent future injuries.
Low-Risk vs High-Risk Stress Fractures
Not all stress fractures are equal. Location determines the risk of serious complications:
- Low-risk sites (good blood supply, compression force): metatarsal shafts, fibula, medial tibial shaft, first rib — typically heal with 6–8 weeks relative rest
- High-risk sites (poor blood supply, tension force, or high-load area): navicular, anterior tibial cortex (the "dreaded black line"), femoral neck, fifth metatarsal (Jones fracture), sesamoids — require more aggressive management (boot, crutches, sometimes surgery)
Why Athletes Get Stress Fractures
The bone stress injury continuum runs from stress reaction (bone oedema without fracture) through to complete fracture. Risk factors include:
- Sudden increase in training load (volume, intensity, surface change)
- Low bone density (history of fractures, eating disorders, female athlete triad)
- Vitamin D and calcium insufficiency
- Low energy availability — the "relative energy deficiency in sport" (RED-S) framework
- Running biomechanics — overstriding, high impact loading, foot pronation
- Inadequate footwear or worn-out shoes
Rehabilitation Phases
Phase 1 — Protected loading (Weeks 0–4): Relative rest from the offending activity. Maintain fitness with swimming, upper body conditioning, and pool running. Medical management including bone health review.
Phase 2 — Graduated weight-bearing (Weeks 4–8): Begin walking and low-impact conditioning. Pain-free walking is the prerequisite for progressing. Address biomechanical risk factors.
Phase 3 — Return to running (Weeks 6–12): Progressive walk-run intervals based on a structured return-to-run program. Running load is determined by symptom response — no pain during or after exercise.
Phase 4 — Full training (Weeks 8–16+): Full training load restoration. Ongoing bone strength and load management education to prevent recurrence.
High-risk stress fractures — see a doctor urgently if:
- • Pain is severe and constant, not just with activity
- • You have pain in the hip or groin after running (possible femoral neck stress fracture)
- • You cannot weight-bear
- • You have a history of eating disorder, amenorrhoea, or low bone density

Frequently Asked Questions
What is a stress fracture?
A stress fracture is a small crack in a bone caused by cumulative repetitive loading, rather than a single traumatic event. The bone's remodelling capacity cannot keep up with the rate of damage accumulation. They occur most commonly in the metatarsals (foot), tibia (shin), fibula, navicular, and femoral neck.
How is a stress fracture diagnosed?
X-rays often appear normal in the first 2–3 weeks. Bone scan (high sensitivity) or MRI (high specificity and no radiation) are the preferred imaging modalities for suspected stress fractures. MRI is increasingly the gold standard as it can grade severity and identify bone marrow oedema (stress reaction) before a full fracture develops.
What causes stress fractures in runners?
The "bone stress injury cycle" is driven by training load, bone strength, and recovery. Common contributors include: rapid increase in training volume or intensity, transition to harder surfaces, nutritional deficiencies (low energy availability, vitamin D, calcium), inadequate rest, poor running biomechanics, and low bone density.
Can I do anything while a stress fracture heals?
Yes. Physiotherapy during the healing phase focuses on: maintaining cardiovascular fitness with pool running, swimming, or cycling (where pain-free); strength training for the upper body and non-affected limbs; addressing biomechanical risk factors; nutritional optimisation; and planning a structured return-to-running program.
