PROXIMAL FEMORAL NAIL ANTIROTATION INTERNAL FIXATION IN TREATING INTERTROCHANTERIC FEMORAL FRACTURES OF ELDERLY SUBJECTS

This study compared the effect of dynamic hip screw (DHS) and proximal femoral nail anti-rotation (PFNA) in the treatment of intertrochanteric femoral fractures of elderly subjects and evaluated the effect of PFNA internal fixation. Two hundred and sixteen elderly patients with intertrochanteric femoral fracture who received treatment in Binzhou Medical University Hospital, Shandong, China were selected. They were divided into a PFNA group which adopted PFNA for internal fixation and a DHS group which adopted DHS for internal fixation, 108 cases in each group. The physical condition of the patients in the two groups were recorded on admittance. The fracture was typed according to Evans Jensen classification criteria. Patients were followed up after surgery to evaluate the postoperative recovery and Harris score of hip joint function. Except for the length of hospital stay, the length of incision, interoperative blood loss, volume of drainage and duration of operation of the PFNA group were all superior to those of the DHS group (P<0.05); the incidence of postoperative complications of the PFNA group was lower than that of the DHS group (P<0.05); the early Harris score of the treatment was superior to that of the DHS group, and there was no remarkable difference (P>0.05). PFNA has more advantages than DHS in treating intertrochanteric femoral fracture of the elderly; hence it is worth wide application in clinical use.
