Stress Fracture in Runners

A stress fracture is a small crack in a bone that develops when bone breakdown outpaces bone remodeling. Common sites for runners: tibia, metatarsals (especially the 2nd and 3rd), navicular, and femoral neck. Some — femoral neck and navicular — are 'high-risk' and require careful management.
