One hundred consecutive patients who had Howmedica ABG total hip replacements, a system in which the femoral stem and the acetabular component are hydroxyapatite coated, during the period from September 1989 to January 1991 were studied prospectively. Clinical assessment using the d'Aubigné score showed that 96 patients had an excellent score at a minimum of 2 years from the operation. Radiographic analysis, based on DeLee and Charnley criteria for the acetabular cup and on Gruen criteria for the femoral stem, showed equally good results. There was good initial stability of the cup and the metaphyseal portion of the stem, with a secondary increase of load transmission in Zones 2 and 6 with cortical and cancellous thickening.
对1989年9月至1991年1月期间连续100例行豪美迪克全髋关节置换术（一种股骨柄和髋臼部件均涂有羟基磷灰石的系统）的患者进行了前瞻性研究。采用德洛内评分进行临床评估显示，96例患者术后至少2年时评分优异。基于德利和查恩利髋臼杯标准以及格鲁恩股骨柄标准进行的影像学分析显示结果同样良好。髋臼杯和股骨柄干骺端部分初始稳定性良好，随着皮质骨和松质骨增厚，2区和6区的负荷传递继发性增加。
