Forty-five Furlong hydroxyapatite-coated total hip replacements were reviewed at an average of 71 months (46-89) after surgery. Patient's average age at surgery was 46 years (31-50). The average Harris hip score at the time of final review was 89, and 38 hips (84%) had no pain (28) or only slight pain (10). Three hips were revised, none for aseptic loosening. Two cups were loose. The remainder of the cups and all the stems were radiographically stable with positive evidence of bone ingrowth and no signs of impending failure. One cup showed definite wear of the polyethylene liner. Focal progressive osteolytic lesions occurred in the calcar region in 3 stable hips (7%). To date the Furlong hydroxyapatite-coated implant has produced encouraging results in this group of young patients, although longer follow-up is needed to determine its durability.
对45例接受弗隆羟基磷灰石涂层全髋关节置换术的患者进行了回顾性研究，术后平均随访71个月（46 - 89个月）。患者手术时的平均年龄为46岁（31 - 50岁）。末次随访时的平均Harris髋关节评分是89分，38例髋关节（84%）无疼痛（28例）或仅有轻微疼痛（10例）。3例髋关节进行了翻修，均非因无菌性松动。2个髋臼杯松动。其余髋臼杯和所有股骨柄在影像学上稳定，有骨长入的阳性证据且无即将发生失败的迹象。1个髋臼杯显示聚乙烯内衬有明确磨损。3例稳定髋关节（7%）的股骨距区域出现局限性进行性骨质溶解病变。迄今为止，弗隆羟基磷灰石涂层植入物在这组年轻患者中取得了令人鼓舞的结果，不过需要更长时间的随访来确定其耐用性。
