双极人工股骨头置换治疗高龄不稳定型股骨粗隆间骨折疗效观察

目的探讨双极人工股骨头置换手术治疗高龄不稳定型股骨粗隆间骨折患者的临床疗效。方法对平均手术年龄为86．5岁的16例高龄不稳定型股骨粗隆间骨折的患者采用手术置换双极人工股骨头,并且重塑股骨矩,股骨矩破坏缺损处灵活运用骨水泥弥补。结果16例患者有12例完全或接近恢复到术前行走水平,随访中没有发现感染及机械性松动,没有术后脱位发生,髋关节屈曲80°-110°。结论人工股骨头置换作为内固定治疗的补充,是治疗高龄不稳定型股骨粗隆间骨折的可选方法。

Observation of Efficacy on Unstable Intertrochanteric Fracture Treated by Dipolar Artificial Femoral Head Replacement in Aged People

Objective To explore the efficacy of bipolar artificial femoral head replacement on unstable intertrochanteric fracture in aged people. Methods Bipolar artificial femoral head replacement was adopted in 16 cases of unstable intertrochanteric fracture for the patents with mean operation age of 86.5 years. Additionally, the femoral calcar was reshaped and bone cement was used flexibly for femoral calcar defect. Results 12 of 16 cases were recovered completely or near to the walking level as that before operation. In follow - up, there was no infection and mechanic loosening and post - operative dislocation happened. The hip flexion was in the range from 80° to 110°. Conclusion Artificial femoral head replacement serves as supplement of the internal fixation treatment, which is optional for unstable intertrocbanteric fracture in the aged people.
