LISS和PFNA治疗老年人股骨转子间骨折的对比研究

Comparative Research of LISS and PFNA in the Senior Intertrochanteric Fracture

目的 对比分析反向股骨远端微创内固定系统（1ess invasive stabilization system , LISS） 和股骨近端螺旋刀片抗旋髓内钉（ proximal femoral nail antirotation blade , PFNA）治疗老年人股骨粗隆间骨折的临床疗效. 方法 回顾笔者医院2009年12月~2012年12月收治的48例患者. 根据不同的手术方式分为：LISS组（ n=24例）和PFNA组（ n=24例） ,通过两组的手术时间、术中出血量、骨折愈合时间、Harris功能评分及相关并发症来评估两者的疗效. 结果 随访10~23个月后,两组的术后并发症、骨折愈合时间及末次随访功能评分差异无统计学意义,LISS组相对PFNA组的手术切口较长、手术时间较长、术中失血量较多. 结论 LISS和PFNA治疗股骨粗隆间骨折均可取得较好的疗效,对于老年人的股骨粗隆间骨折PFNA具有优势.

Objective To compare the clinical efficacy of less invasive stabilization system （ LISS） and proximal femoral nail antiro-tation blade （ PFNA） in the senior intertrochanteric fractures .Methods A total of 48 patients of intertrochanteric fractures from Decem-ber 2009 to December 2012 were retrospectively analyzed .The patients were divided into two groups according to the different methods of operation：LISS group （n=24） and PFNA group （n=24）.Operation time, intraoperative blood loss, fracture healing time, Harris func-tion scores and incidence of complications after operation were compared , in order to evaluating the effect of two methods .The analysis of viariace,LSD-T test and χ2 test were used for data analysis .Results The range of followed -up was 10-23 months, There was not sta-tistically significant between two groups , according to incidence of complications after operation , fracture healing time and Harris function scores , but LISS group got longer incision , longer surgery time and more intraoperative blood loss .Conclusion LISS and PFNA are both effective methods to treat senile intertrochanteric fractures , compared with LCP , PFNA is an ideal method of senile intertrochanteric frac-tures.
