股骨粗隆间骨折内固定失效原因分析及对策

目的探讨股骨粗隆间骨折内固定失效原因及治疗对策。方法回顾总结我院2003～2009年行手术治疗的123例股骨粗隆间骨折病例,按Evans分型,分析各型骨折内固定失效原因,内固定方式与内固定失效类型及发生率情况。结果 123例均得到随访,有23例骨折内固定失效,其中稳定型骨折内固定失效5例,不稳定型骨折内固定失效18例;发生率为18.69%。失效类型：髋内翻、股骨颈短缩、内固定物断裂导致骨折畸形。不稳定型骨折内固定失效发生率远高于稳定性骨折,而钉板系统内固定失效发生率远高于髓内系统。钉板系统中近端解剖钢板内固定失效发生率高于动力髋螺钉（DHS）。结论对各类型骨折特点认识不够从而导致内固定方式选择不当;骨质疏松症患者术后过早负重;术者操作不当。

Failure cause and treatment countermeasure of internal fixation on femoral intertrochanteric fracture

Objective To discuss the failure cause and treatment countermeasure of internal fixation on femoral intertrochanteric fracture.Methods Clinical data of 123 patients with femoral intertrochanteric fracture admitted into our hospital from 2003 to 2009 were retrospectiverly collected,analyzing the failure causes of operation,methods of internal fixation,failure types of internal fixation and failure incidence of internal fixation.Results All the patients were followed up for 1.5 to 36(mean,24.3) months.Totally...
