远端锥形组配式生物股骨柄在股骨翻修术中的应用

目的探讨使用远端锥形组配式生物股骨柄（MP）在股骨翻修中应用的临床效果及经验。方法回顾性分析了21例采用MP远端锥形组配式生物股骨柄翻修患者的影像及临床效果，平均随访2年以上，影像上术前、术后及每次随访时均常规摄髋关节正侧位，临床效果使用Harris评分评测，调查患者满意度。结果Harris评分由术前的平均（56．2±25．2）分上升到术后的（85．3±13．2）分，最后一次随访时上升到（89．2±11．5）分，患者满意度90．5％。20例患者中术后X线片评价上：可观察到骨缺损区的修复，而没有近端骨质吸收和透亮线的增加，锥度连接处没有发生不良并发症，这20例患者术后即获得初次稳定性，另1例因感染未彻底清除而发生了假体下沉进行了再次翻修手术。结论MP远端锥形组配式生物股骨柄翻修取得了令人鼓舞的结果，远端生物固定的理念可以解决绝大多数少于Paprosky ⅢB的骨缺损患者。

Femoral revision with a distal tapered modular stem

Objective As primary total hip arthroplasties(THA) become more common in younger,physically active patients,the number of revision arthroplasties will also increase.Femoral bone loss,joint instability and possible increased infection rate remain a great challenge for a surgeon performing revision arthroplasty of the hip.The severe proximal femoral bone loss indicates the use of revision stems with a distal fixation.To summarize the application of clinical results and experience of MP distal tapered modular ...
