How Long Does a Stress Fracture Take to Heal?
Quick Answer
6–8 weeks for most stress fractures. Low-risk fractures in the tibia or metatarsals heal in 6 weeks, while high-risk locations like the hip or navicular may take 12–20 weeks.

Quick Answer
Most stress fractures heal within 6–8 weeks with rest and reduced weight-bearing activity. The exact timeline depends heavily on the fracture location, severity, and whether it is classified as low-risk or high-risk.
Healing Timeline by Location
| Location | Risk Level | Healing Time | Weight-Bearing |
|---|---|---|---|
| Metatarsal shaft (foot) | Low | 6–8 weeks | Walking boot, partial weight-bearing |
| Tibial shaft (shin) | Low | 6–8 weeks | Activity modification, possible boot |
| Fibula | Low | 4–6 weeks | Usually weight-bearing as tolerated |
| Calcaneus (heel) | Low | 6–8 weeks | Walking boot or cast |
| Femoral neck (hip) | High | 8–14 weeks | Non-weight-bearing; may need surgery |
| Navicular (foot) | High | 8–12 weeks | Non-weight-bearing cast 6–8 weeks |
| Fifth metatarsal base (Jones) | High | 10–20 weeks | Non-weight-bearing; often requires surgery |
| Anterior tibial cortex | High | 8–12 weeks | Prolonged rest; may need surgical fixation |
| Medial malleolus | High | 8–12 weeks | Non-weight-bearing; possible surgery |
High-risk stress fractures are prone to delayed healing, nonunion, or complete fracture and often require more aggressive treatment.
Return-to-Activity Timeline
| Phase | Timeline | Activity Level |
|---|---|---|
| Acute rest | Weeks 1–2 | Complete rest from impact activities; cross-train with swimming or cycling if pain-free |
| Protected activity | Weeks 2–6 | Walking boot or reduced weight-bearing as directed |
| Gradual return | Weeks 6–8 | Pain-free walking; begin light jogging on soft surfaces |
| Progressive loading | Weeks 8–12 | Increase distance and intensity by 10% per week |
| Full return | Weeks 10–16 | Return to sport-specific training and competition |
Athletes should not return to running or impact activity until they can walk briskly for 30 minutes without pain.
Factors That Affect Healing Time
- Location: High-risk sites (navicular, femoral neck, fifth metatarsal base) have poorer blood supply and heal slower.
- Severity: A stress reaction (pre-fracture bone edema) heals in 2–4 weeks, while a complete stress fracture takes 8+ weeks.
- Nutrition: Inadequate calcium (<1,000 mg/day) and vitamin D (<600 IU/day) impair bone healing.
- Hormonal status: Low estrogen (female athlete triad/RED-S) significantly delays healing.
- Age: Older adults have slower bone remodeling and longer recovery.
- Compliance: Continuing to run or play through pain can convert a stress fracture into a complete fracture.
Tips for Faster Healing
- Follow weight-bearing restrictions strictly. Premature loading is the most common cause of delayed healing.
- Ensure adequate daily intake of calcium (1,000–1,300 mg) and vitamin D (1,000–2,000 IU).
- Maintain cardiovascular fitness with non-impact activities: swimming, cycling, or upper-body workouts.
- Use a bone stimulator if recommended by your orthopedist, particularly for high-risk fractures.
- Address underlying causes: training errors, improper footwear, biomechanical issues, or nutritional deficiencies.
- Get medical imaging (MRI or bone scan) to confirm healing before returning to impact activities.
