PFNA和DHS治疗老年性股骨粗隆间骨折的疗效比较

摘要

Objective To explore the significance of optional internal fixations of senile femoral intertrochanteric fractures by comparing the effects of proximal femoral nail anti-rotationC PFNA bnd dynamic hip screw( DHS X Methods From Feb 2004to Feb 2009, 58 cases with intertrochanteric fractures were divided into DHS( 30 cases )and ( 28 cases ) groups. The data of each group were collected for statistical analysis on the following aspects:operative time, blood loss, intraop-erative and post-operative complications, clinical healing of fracture and post-operative restored function. Result The difference of DHS and PFNA groups had more statistically significance* .PO.05 )on the mean operation time、blood loss、 intraoperative and post-operative complications and clinical healing of fracture . PFNA group was much better than DHS group.The difference of DHS and PFNA groups had no statistically significance(P＞0.05 )on post-operative restored function. Conclusion PFNA was designed more reasonably than DHS, less invasive and more reliable. PFNA was one of satisfactively optional internal fixations.%目的 比较PFNA和DHS治疗老年性股骨粗隆间骨折疗效,探讨内固定选择在老年股骨粗隆间骨折治疗中的意义.方法 2004年2～至2009年2月随机分别采用动力髋螺钉(DHS和防旋型股骨近端髓内钉(PFNA)2种内固定方法治疗58例老年股骨粗隆间骨折患者,PFNA固定28例,DHS固定30例,从手术用时、术中出血量、术中术后并发症发生率、骨折愈合时间、术后疗效等方面比较.结果 2组患者在平均手术用时、术中出血量、术中术后并发症发生率、骨折愈合时间等方面差异有统计学意义(P＜ 0.05 ),PFNA组优于DHS组；在术后疗效方面2组差异无明显统计学意义(P＞ 0.05).结论 PFNA较DHS设计更合理,操作微创,固定牢固,是治疗老年性股骨粗隆间骨折的理想方法之一.
