Between 1985 and 1990, 108 consecutive Harris-Galante I (Zimmer, Warsaw, IN) total hip arthroplasties were performed by four surgeons at a single hospital. At the time of follow-up evaluation, 80 hips were available for review. The mean rate of linear wear was 0.15 mm/y, mean rate of three-dimensional femoral head displacement was 0.21 mm/y, and mean rate of volumetric wear was 121 mm3/y. Eight hips (10%) in this series had radiologic osteolysis around either the femoral or acetabular component. A significantly greater volumetric wear rate was found in patients who were younger, those with a higher activity level, those who received a 32-mm-diameter femoral head, and those with vertical orientation of their acetabular component. No relationship could be made with patient weight, gender, Harris hip score, or cup diameter.
1985年至1990年间，一家医院的四位外科医生连续进行了108例Harris-Galante I型（Zimmer公司，印第安纳州华沙）全髋关节置换术。在随访评估时，有80例髋关节可供检查。线性磨损的平均速率为每年0.15毫米，股骨头三维位移的平均速率为每年0.21毫米，体积磨损的平均速率为每年121立方毫米。该系列中有8例（10%）髋关节在股骨或髋臼假体周围出现了放射性骨溶解。在年龄较小、活动水平较高、接受32毫米直径股骨头以及髋臼假体呈垂直方向的患者中，发现了显著更高的体积磨损率。患者体重、性别、Harris髋关节评分或髋臼直径之间没有关联。
