目的:探讨双极人工股骨头置换术治疗老年人不稳定型股骨转子间骨折的疗效。方法:对38例老年人(年龄71～89岁)不稳定型股骨转子间骨折患者采用双极人工股骨头置换术治疗,其中32例存在一种以上的合并症。结果:术中无死亡,切口无感染。38例均于术后1周开始下地行走,无髋关节脱位,3例发生深静脉血栓形成,3例术后下肢长度不等长。术后1年Harris评定优20例,良15例,优良率为92%;2例死于其他病症。结论:不稳定型股骨转子间骨折的高龄患者选用双极人工股骨头置换术治疗疗效可靠,并发症少。

Objective：To investigate the effect of dipolar artificial femoral head replacement in treatment of unstable intertrochanteric hip fractures in elderly patients. Methods： Thirty-eight patients （age range 71-89 ） with unstable intertrochanteric hip fractures were treated by dipolar artificial femoral head replacement. Thirty-two of them had more than one complication. Results： No death or incision infection occurred in the operation. All the patients began to walk one week after the operation. No dislocation of hip was observed; 3 cases developed deep vein thrombosis and the legs were not equilong in 3 cases. The results were excellent in 20 cases and good in 15 cases according to Harries standard one year after the operation. Two patients died of other diseases. Conclusions： The dipolar artificial femoral head replacement is an effective and reliable technique for treatment of intertrochanteric hip fractures in aged patients and has few complications.
