组合式外固定架治疗老年股骨转子间骨折

Hybrid External Fixation in Treating Femoral Intertrochanteric Fractures of the Elderly Patients

目的：探讨组合式外固定架治疗老年股骨转子间骨折的疗效。方法：自2006年1月至2008年10月，采用组合式外固定支架治疗老年股骨转子间骨折16例，年龄63～101岁，平均76岁。骨折按Evans分型：Ⅰ型4例，Ⅱ型7例，Ⅲ型3例，Ⅳ型2例，12例合并有内科疾病。结果：随访6～24月，平均18月，所有病例均获骨性愈合，优良率93．8％。无卧床并发症和下肢深静脉血栓形成发生。结论：组合式外固定架治疗老年股骨转子间骨折符合生物力学原理，患者可以早期活动而减少卧床并发症，且手术创伤小，患者容易接受，是一种值得推荐的治疗手段。

Objective： To discuss the curative effect of application of hybrid external fixation in the treatment of intertrochanteric fractures of the elderly patients. Method： From January 2006 to October 2008, 16 aged people with intertrochanteric fractures were treated with the hybrid external fixationt the average age of the patients was 76 years （range 63 - 101 ）. According to Evans classification, Ⅰ type 4 cases, Ⅱ type 7 cases, Ⅲtype 3 cases, Ⅳtype 2 cases1 twelve patients had medical conditions. Result： All cases were followed -up for 18 months in average （range 6 -24 months） , all patients acquired bony union, 93.8% were classified as excellent and good. There were no complications associated with stage of immobilization and deep venous thrombosis. Conclusion ： Application of hybrid external fixator in the treatment of intertrochanteric fracture in the elderly consistents with the principle of biomechanics, less surgical trauma, can achieve early exercise and decrease the complications associated with lying in bed, and easily be adopted. So is a recommendable management.
