DHS和PFN治疗股骨粗隆下骨折的疗效对比分析

目的对比分析采用股骨近端髓内钉（PFN）和加压滑动鹅头钉（DHS）治疗股骨粗隆下骨折疗效。方法 42例股骨粗隆下骨折患者,按照Seinsheimer分型：ⅡB型10例,ⅡC型13例,ⅢA型16例,ⅢB型3例,分别采用DHS和PFN固定治疗。对比分析术中情况及术后并发症。结果经9~18个月随访,平均12.2个月,PFN组较DHS组在手术时间、出血量、切口长度等方面均有优势;术后并发症PFN组较DHS组少;按照Harris髋关节评分标准,术后PFN组和DHS组相比较,无明显差异。结论 PFN在治疗股骨粗隆下骨折中是一种理想的固定材料。

Comparative analysis of dynamic hip screw and proximal femoral nail in treatment of subtrochanteric femoral fracture

Objective To analyze and compare the clinical efficacy of dynamic hip screw（DHS） and proximal femoral nail（PFN） for subtrochanteric femoral fracture.Methods Totally 42 cases of subtrochanteric femoral fracture were subdivided into type IIB（n=10）,type IIC（n=13）,type IIIA（n=16） and type IIIB（n=3） based on Seinsheimer classification.DHS and PFN were applied respectively and the intra-operation condition and postoperative complications were analyzed.Results All patients were followed up for 9~18 months（averaged 12.2 months）.PFN group had better effect than DHS group on many aspects such as operation time,blood loss and incised length.Meanwhile,PFN group had fewer postoperative complications than DHS group.There was no significant difference between two groups according to Harris criterion.Conclusion Proximal femoral nail is a useful device in the treatment of subtrochanteric femoral fracture.
