Abstract:

BACKGROUND: Proximal femoral nail-antirotation (PFNA) is a novel internal fixation system of AO/ASIF to reduce complication. It displays advantages because of minimal invasion and antirotation design.
OBJECTIVE: To compare the curative effect between PFNA and prosthetic replacement for the treatment of intertrochanteric fractures in the elderly.
METHODS: From July 2008 to December 2009, 37 cases of femoral intertrochanteric fracture in elderly patients were selected from Department of Orthopedics, Sun Yat-sen Memorial Hospital affiliated Sun Yet-san university, including 16 treated with PFNA fixation and 21 with prosthetic replacement (18 artificial femoral head, and 3 total hip replacement).
RESULTS AND CONCLUSION: No statistical differences were observed in terms of hospitalization duration, ambulation time, postoperative complications and postoperative hip function between two groups (P > 0.05); intraoperative bleeding and operation time in PFNA fixation group were superior over prosthetic replacement group (P < 0.05). Both the PFNA fixation and prosthetic replacement have good clinic curative effects in treatment of femoral intertrochanteric fracture in the elderly, but PFNA fixation has advantages on the reduction of operation time and intraoperative bleeding.
