PFNA内固定术应用于老年股骨粗隆间骨折的临床疗效观察

Clinical efficacy of PFNA internal fixation on femoral trochanter fracture in the elderly

目的探讨股骨近端抗旋髓内钉（PFNA）内固定术应用于老年股骨粗隆间骨折的临床效果。方法选取该院2013-01—2015-01收治的股骨粗隆间骨折老年患者100例，根据数字奇偶法随机分为对照组和观察组，各50例。对照组采用股骨近端重建钉（PFN）内固定术治疗，观察组采用PFNA内固定术治疗，观察比较两种手术方式的治疗效果。结果观察组疗效优于对照组，两组比较差异有统计学意义（P〈0．05）；观察组的手术时间、术中出血量、住院时间、骨折愈合时间均少于对照组，差异有统计学意义（P〈0．01）。结论PFNA内固定术在老年股骨粗隆间骨折中治疗效果显著，操作简便，减少手术时间和出血量，有效固定骨折，加快骨折愈合，值得临床推广应用。

Objective To explore the clinical efficacy of internal fixation of proximal femoral nail anti-rota- tion（PFNA） on femoral trochanter fracture in the elderly patients. Methods One hundred elderly patients with femo- ral intertrochanteric fracture in our hospital from January 2013 to January 2015 were randomly divided into the control group and the observation group, with 50 cases in each group. The control group was subjected to the reconstruction treatment of proximal femoral nail（ PFN）, and the observation group received the therapy of PFNA. The clinical effi- cacies of the two kinds of operation methods were compared. Results The therapeutical effect of the observation group was better than that of the control group（P 〈 0. 05 ）. The operation time, intra-operative blood loss, hospitali- zation and fracture healing time in the observation group were significantly less than those in the control group（ P 〈 0. O1 ）. Conclusion Internal fixation of PFNA is highly efficacious and simple for the elderly patients with femoral trochanter fracture.
