title: [Stress fracture of the femoral neck in a marathon runner. Case report and review of the literature].
abstract: Stress fracture of the femoral neck is rare, and the conditions in which it occurs are complex. An unusually high, rhythmically acting force resulting from body weight and muscle tension leads to decompensation of the dynamic equilibrium otherwise prevalent in bone metabolism in conditions of adaptation. Even small differences in leg length predispose to fracture of the longer leg, owing to the increased muscular activity. Bone scanning is helpful in diagnosis when no signs of fracture are revealed by conventional radiography. Internal fixation that will allow weight-bearing should be attempted. In this case report an instance of this type of fracture in a marathon runner is presented.
