Stress fractures in 51 runners
Clinical Orthopaedics and Related Research
|July 1, 1984
Summary
Running stress fractures are common, especially in the tibia. Factors like training mileage, surface, and foot type increase risk, while rest is key for recovery.
Area of Science:
- Sports Medicine
- Orthopedics
- Biomechanics
Background:
- Stress fractures are common injuries in runners.
- Understanding risk factors and prevention strategies is crucial for athletes.
Purpose of the Study:
- To investigate risk factors for stress fractures in runners.
- To explore methods for preventing stress fractures in this population.
Main Methods:
- A prospective study initiated in 1976.
- Involved 51 runners who sustained 57 stress fractures.
- Data collected on fracture location, history, and training habits.
Main Results:
- Tibial fractures were most frequent (25), followed by fibula (12) and metatarsal (8).
- Risk factors included pes planus, >20 miles/week training, hard surfaces, and training changes.
- No correlation found with generalized musculoskeletal laxity or tightness.
- Radiographs were positive in 44/51 patients; bone scans were positive in all five tested.
- Average rest period before resuming running was 7.4 weeks.
Conclusions:
- Identified key risk factors for running-related stress fractures.
- Highlights the importance of training modifications and surface choice.
- Emphasizes the role of imaging in diagnosis and the need for adequate rest for recovery.
