This retrospective review was conducted to determine the incidence and minimum 5-year follow-up of varus placement of a tapered, proximally plasma-sprayed, titanium femoral component. Twenty-six (2.4%) of 1080 components were placed in > or = 5 degrees of varus in primary cementless total hip arthroplasty at one institution. Harris hip scores improved an average of 50 points. One stem was revised for malposition at 2.5 years, yet was well-fixed by radiographic criteria. Survival with aseptic loosening as an end-point is 100% with an overall femoral component survival of 96% at an average 10-year follow-up. A tapered, titanium component is reliably placed into appropriate position and is forgiving as to varus implant position.
进行这项回顾性研究以确定在近端进行等离子喷涂的锥形钛制股骨假体内翻植入的发生率及至少5年的随访情况。在一家机构进行的初次非骨水泥全髋关节置换术中，1080个假体中有26个（2.4%）的内翻角度≥5度。Harris髋关节评分平均提高了50分。1个假体柄在2.5年时因位置不当进行了翻修，但根据影像学标准其固定良好。以无菌性松动为终点的生存率为100%，在平均10年的随访中，股骨假体的总体生存率为96%。锥形钛制假体能够可靠地放置在合适位置，对内翻植入位置具有一定宽容度。
