A stress fracture is a small crack in a bone. They often develop from overuse, such as from high-impact sports like distance running or basketball. When muscles are overtired (fatigued), they are no longer able to absorb the shock of repeated impacts. When this happens, the muscles transfer the stress to the bones, creating a small crack or fracture.
Most stress fractures occur in the weight-bearing bones of the foot and lower leg. The most common sites are the second and third toes (metatarsals) of the foot. Stress fractures are also common in the heel (calcaneus), the outer bone of the lower leg (fibula), and the navicular, a bone on the top of the midfoot.
Our Approach to Stress Fracture
Stress fractures generally heal on their own with simple measures, such as avoiding activities that put stress on the area. In some cases, however, surgery is needed to help the fracture heal properly.
Many stress fractures occur in the foot or lower leg. Our team includes highly trained orthopedic surgeons who specialize in that area, as well as podiatrists, physical therapists and pedorthists (specialists in modified footwear and supportive devices for the lower leg). Our goals are to relieve pain and restore mobility, so patients can return to their normal lives and the activities they enjoy. We offer doctor's appointments, medical imaging and physical therapy in one convenient location.
