A series of 33 Stanmore total hip replacements with aseptic loosening was compared to a matched control series without loosening. Risk factors were previous hip surgery and osteopenia of the proximal femur. Biomechanical factors, notably varus position of the femoral stem and insufficient cementation, were of significance for the implant loosening. Alteration of the operative technique is recommended, emphasizing a correct valgus or neutral position of the femoral component and improved cementation.
将33例出现无菌性松动的斯坦莫尔全髋关节置换病例与一组配对的无松动对照病例进行了比较。危险因素为既往髋关节手术和股骨近端骨质减少。生物力学因素，尤其是股骨干内翻位和骨水泥固定不充分，对植入物松动具有重要影响。建议改变手术技术，强调股骨部件正确的外翻或中立位以及改进骨水泥固定。
