The rate of excellent and good functional recovery of hip was 94.0%. Postoperative internal-fixation-related complications occurred in 31 cases, including hip varus in 14 cases who had posterior intertrochanteric fragments, delayed union of fracture in 12 cases who had fractured calcar and lesser trochanter and massive dissection of soft tissues, and cutting-out of lag screws in five cases, three of whom had to receive prosthetic replacement.
