The stress fracture is a disease which results from the application of an abnormal stress to the normal bone by the action of the constant and repeated muscular pull. prior to the early 1960s, most reports of stress fractures were from military installation, however, with the recent increase in participation in leisure and professional athetic activities such fractures have vecome more common among civilians.

We treated two cases of stress fractures of the supracondylar region of the femur in runners. One patient was treated conservatively, but the other with displacement was treated operatively. To our knowledge, no previous cases of this nature have been reported.
