DHS Gamma钉与PFN治疗股骨转子间骨折的疗效分析

Treatment of Femoral intertrochanteric Fractures with Dynamic Hip Systerm(DHS)&Gamma Nail & Proximal Femoral Nail(PFN)

目的:探讨动力髋螺钉(DHS)与Gamma钉以及股骨近端髓内钉(PFN)治疗转子部骨折的临床经验,提高治疗转子部骨折的治疗水平。方法:2008年5月至2011年5月选用进口DHS,Gamma钉与AO产PFN治疗112例转子部骨折病人,手术使用骨科牵引床,C型臂影象增强器,DHS采用闭合复位切开内固定,Gamma钉和PFN采用闭合复位锁钉技术。结果:DHS组51例病人中50例3-4个月全部骨性愈合,髋关节屈伸活动恢复95%以上,旋转活动恢复恢复85%。一例出现股骨头切割及髋内翻畸形。Gamma钉组39例病人中1例髋内翻畸形并股骨外侧疼痛,全部病例3-4个月内骨性愈合。PFN组23例病人22例3-4个月全部骨性愈合,关节功能良好。结论:动力髋螺钉(DHS)与Gamma钉以及股骨近端髓内钉(PFN)是治疗转子部骨折的有效方法,三者各有其优缺点。根据三者生物力学性能的不同选择不同病例,可促进骨折愈合减少并发症。

Objective：To report the clinical experimence in treating femoral intretrochanteric fractures with ynamic hip systerm（DHS） Gamma nail proximal femoral nail（PFN）.Methods：112 cases were treated with dynamic hip systerm（DHS） Gamma nail proximal femoral nail（PFN） respectively.Traction table G-arm image intensifier were used with close reduction and interlocking.Results：All fractures healed withing 3-4 months with good functional recovery of hip joint.Conclusion：DHS,Gamma nail and PFN are all effective methods to treat femoral intertrochanteric fractures.
