The Gamma nail was introduced fot treatment of peritrochanteric fractures with the theoretical advantage of transmitting weight closer to the calcar than does the dynamic hip screw. Forty consecutive peritrochanteric fractures were treated using the Asian type of the Gamma nail during the period from October, 1992 to March, 1993. Except in one case with a comminuted fracture involving the subtrochanteric region, distal locking screws were not used. In one case, external rotation of the lower extremity was revealed clinically and radiologically. However, no intraoperative and post-operative fractures occurred. Neigher proximal migration nor superior cutting-out of the lag screw was observed. On the basis of our experience, we believe that Gamma nailing could be the treatment of choice for peritrochanteric fractures of the femur.
