This paper evaluates clinical results of peritrochanteric fractures treated using the Gamma nail. The Gamma nail was introduced for treatment of peritrochanteric fractures with the theoretical advantage of a load-sharing femoral component which could be implanted using a closed procedure. We used the Gamma nail in 19 fractures from January 1992 to March 1993. Union was achieved in all cases with in a reasonable postoperative period even in comminuted fractures. These cases had shorter convalescence and earlier full weight bearing than the cases treated with dynamic hip screws reported previously from our hospital. The major complication was fracture of the femoral shaft at the distal end of the nail seen in one case at the fourth month postoperatively. Increased anteversion of the femoral neck was seen in some cases. We conclude that the Gamma nail is an advance in the treatment of peritrochanteric farctures.
