[Bone disease with Pain. Stress fracture].

The repetitive mechanical stress that can not break the bone in one time, may cause stress fractures as a consequence of the overuse syndrome. As a sport injury, stress fracture is reported in several parts of the body, mainly lower extremities, and the diagnosis is relatively easy. The physical examination shows tenderness and pain while moving. The evaluation of surrounding structures of the stress fracture is mandatory. Risk factors include female, elderly and individuals with low physical abilities. The proper plan of training for each athlete is important not only to improve performance but also to prevent stress fractures.
