We reviewed the early clinical results of 117 peritrochanteric fractures treated with the Gamma nail. The average age of the patients was 77 years. The mean follow-up period was 264 days. The fractures were grouped into 5 types according to Jensen's classification. There was a significant difference in the sliding of lag screws between stable and unstable fractures. The main post-operative complication was cut out of the lag screw. It is essential to decide their operative indications carefully, because peritrochanteric fractures with fractures at the base of the femoral neck showed poor results.
