PFNA微创治疗不稳定型股骨粗隆间骨折临床分析

Clinical analysis of PFNA minimally invasive treatment of unstable intertrochanteric fractures of femur

目的探讨微创防旋型股骨近端髓内钉(PFNA)治疗不稳定型股骨粗隆间骨折的治疗效果。方法回顾性分析2015年6月至2016年6月不稳定型股骨粗隆间骨折患者76例,观察PFNA治疗的切口引流量、手术出血、手术时间、骨折愈合时间、髋关节功能恢复情况、术后并发症发生情况。结果纳入病例均完成了半年随访,术后均未发生切口的感染、骨折不愈合、下肢静脉血栓形成、髋内翻及内固定松动等情况,术后并发症发生率仅为3.95%,术后半年髋关节功能Harris评分优良率为95.5%。结论 PFNA治疗不稳定型股骨粗隆间骨折术后并发症少,骨折恢复快,疗效确切,是不稳定型股骨粗隆间骨折有效的治疗术式。

Objective To evaluate the effect of minimally invasive proximal femoral nail antirotation （PFNA） in the treatment of unstable intertrochanteric fractures of femur. Methods The clinical data of 76 patients with unstable intertro- chanteric fractures from June 2015 to June 2016 were analyzed retrospectively. The incidence of knife-edge drainage, surgi- cal bleeding, the operation time, healing time, hip function recovery and postoperative complications were recorded. Results All the cases were followed up for six months. No incision infection, nonunion, venous thrombosis of lower extremi- ty, hip varus and flexible internal fixation were found. The postoperative complication rate was only 3.95%. The good and excellent rate of Harris score of hip joint function were 95.5%. Conclusions PFNA is an effective treatment option for un- stable femoral intertrochanteric fractures with less postoperative complications, quicker recovery and better curative effect.
