Internal fixations of proximal femoral nail antirotation versus that of dynamic hip screw for femoral intertrochanteric fracture

Abstract

Objective TO explore and study the clinical effects of the internal fixations of proximal femoral nail antirotation（PFNA） and dynamic hip ＇serew（DHS） for femoral intertrochanteric fracture. Methods 100 patients with femoral intertrochanteric fracture admitted into our hospital from April, 2009 to April, 2013 were selected as study objects and randomly and eqUally divided into two groups. 50 patients （PFNA group） were .treated by the internal fixation of PFNA and the other 50 patients （DHS group） by the internal fixation of DHS. They were followed up for 9-18 months. The curative effects of both groups were observed and compared. Results The： volumes of intraoperative bleeding and of the postoperative drainage were smaller and the postoperative weight-loading walking time and healing time were shorter in the PFNA group than in the DHS group. The Harris hip function scores were increased in both groups after the treatment; the hip function scores, motion ranges, and synthetic scores were increased more but the hip joint score of deformity less in the PFNA group than in the DHSgroup. The incidence of postoperative complications of the PFNA group was 6.0%, which was significantly lower than that of the DHS group （26.0%）, with a statistical difference （P〈0.05）. Conclusions PFNA has better curative effects than DHS in the treatment of femoral intertrochanteric fracture and has greater comparative advantages in intraoperative bleeding volume, postoperative healing time, and weight-bearing walking time. Comparing with DHS treatment, PENA treatment causes fewer postoperative complications and recovers hip joint function better, so it can be the first treatment choice for patients with femoral intertrochanteric fracture.
