动力髋螺钉与股骨近端髓内钉治疗不稳定型股骨粗隆间骨折的临床比较

目的：比较动力髋螺钉（ DHS）和股骨近端髓内钉（ PFNA）两种内固定治疗不稳定型股骨粗隆间骨折的临床疗效。方法自2008年5月至2013年4月间对95例老年股骨粗隆间不稳定型骨折患者进行回顾性研究，患者分为DHS组45例与PFNA组50例，比较两组的手术时间，术中出血量，下地行走时间，骨折愈合时间及髋关节功能等数据。结果 PFNA组和DHS组在手术时间，术中出血量，下地行走时间有显著差异，而在骨折愈合时间无明显差异，对于不稳定型股骨粗隆间骨折， PFNA组的髋关节功能优良率高于DHS组。结论对于不稳定的股骨粗隆间骨折，PFNA系统具有出血少，手术时间短，恢复快等的优点。

Dynamic hip screw and proximal femoral nail in treatment of unstable femoral intertrochanteric fracture

Objective To compare the clinical curative effects of the dynamic hip screw （ DHS ） and the proximal femoral nail （ PFNA ） in the unstable intertrochanteric fracture of the femur .Methods Between May 2008 to April 2013,95 elderly patients of the unstable femoral intertrochanteric fracture in our hospital were enrolled in the study .All the cases were randomly divided into two groups：45 cases were in the DHS group and 50 cases were in the PFNA group .The operation time , intraoperative blood loss , walking time, fracture healing time, the hip joint function and other data of the two groups were compared . Results There were significant differences in the operation time , the intraoperative blood loss , and the＆amp;nbsp;walking time between the PFNA group and the DHS group; but there was no obvious difference in the fracture healing time .As for the hip function restoration of the unstable intertrochanteric fracture , the PFNA group was better than the DHS group .Conclusion In the unstable intertrochanteric fracture , the PFNA system has the advantages of less bleeding , short operation time , and fast recovery .It is worthy of promotion.
