股骨近端防旋髓内钉与动力髋螺钉治疗股骨转子间骨折的疗效比较

The anti-rotation of the proximal femur intramedullary nail and dynamic hip screw for the treatment of intertrochanteric fractures

目的对比分析股骨近端防旋髓内钉与动力髋螺钉治疗股骨转子间骨折的疗效。方法选择2010年1月～2012年1月我院住院治疗的股骨转子间骨折患者72例,全部患者根据治疗方法不同随机分为PFNA组和DHS组各36例,比较两组的疗效。结果 PFNA组术中平均出血量少于DHS组,手术时间也短于DHS组,且PFNA组Harris评分明显高于DHS组(P<0.05)。PFNA组的疗效明显优于DHS组(P<0.05)。结论与DHS内固定术相比,PFNA内固定治疗股骨转子间骨折更具优势,疗效满意,髋关节功能恢复效果好,并发症少,值得推广和应用。

Objective To compare the anti-rotation of the proximal femur intramedullary nail and dynamic hip screw in treatment of intertrochanteric fractures. Methods Seventy-two cases patients with intertrochanteric fracture were randomly divided into the PFNA and DHS groups with each 36 cases, the efficacy were compared between two groups. Results The average blood loss of PFNA group was less than the DHS group, surgery time was shorter than the DHS group, and the PFNA group Harris score was significantly higher than the DHS group （P 〈 0.05）. The effect of PFNA group were significantly better than the DHS group （P 〈 0.05）. Conclusion Compared with DHS fixation, the PFNA has many advantages, hip functional recovery is satisfied, fewer complications, and worthy of promotion and application.
