We treated 546 cases of intertrochanteric fractures with the Gamma nail between April 1996 and March 2004. Intraoperative complications were seen in two patients and postoperative complications in twenty. The former were femoral shaft fracture in two patients and the latter were femoral shaft fracture in six patients, cut out of the lag screw in six, infection in six, pseudoaneurysm in one, and nonunion in one. To prevent shaft fracture and cut out of the lag screw, appropriate techniques are necessary.
