Effect of placement of proximal femoral nail anti rotation on the short-term and long-term efficacy in elderly patients with osteoporotic femoral intertrochanteric fractures

Abstract

Objective To investigate the effect of modified placement of proximal femoral nail anti rotation on the short-term and long-term efficacy in elderly patients with osteoporotic femoral intertrochanteric fractures. Methods The clinical data of 65 elderly patients with osteoporotic femoral intertrochanteric fractures were retrospectively analyzed, 40 patients who were treated by placement of proximal femoral nail anti rotation(PFNA) were selected as the study group, and the other 25 patients who were treated by dynamic hip screw fixation(DHS) were selected as the control group. Followed up for 1 year, the short-term and long-term efficacy, operation time, incision length, intraoperative blood loss, fracture healing time and complications during follow-up were compared between the two groups. Results The differences in the level comparison of efficacy between the two groups after 1 month of operation and during follow-up were significant(P<0.05), but comparison within the groups, the differences were not significant(P<0.05). The operation time, intraoperative blood loss, incision length and fracture healing time in the study group were significantly better than those in the control group(P<0.05), and the incidence rate of complications of the study group was 2.50%, which was significantly lower than that of the control group(20.00%, P<0.05). Conclusions The short-term and long-term efficacy of PFNA is remarkable compared with that of DHS, with small trauma, less postoperative complication, is helpful for postoperative recovery of elderly patients with osteoporotic intertrochanteric fractures, which has good application scenarios.
