[Epiphysiolysis of the upper femur. Apropos of 53 cases in adolescents].

Authors studied 53 cases of slipped upper femoral epiphysis. They analyse principally the result of the surgical treatment. They find 15% of bad results due essentially to therapeutic errors leading to chondrolysis and necrosis. Extra-articular fixation by two screws is the treatment of choice in most cases. Intra-articular fixation, Howorth procedure, gives good result when screwing is impossible. Orthopedic reduction is banned in gradual slipping, but is considered as good solution in acute slipping. When the deplacement considered as good solution in acute slipping. When the deplacement is more than 90 degrees, with knited growth plate, we propose an corrective intertrochanteric osteotomy. Authors haven't experience of Dunn's procedure.
