The survival of 77 cementless total hip arthroplasties using a Bi-Metric femoral stem and two types of acetabular components was analysed in 55 patients with juvenile chronic arthritis. The patients were treated between 1986 and 1996. Their mean age was 8.0 years at the onset of the disease and 28.1 years at the time of surgery. The mean follow-up period was 9.6 years. Follow-up evaluations were conducted 3 months and 1, 4, 8, 12 and 16 years post-operatively. The endpoints of survival analysis were revision surgery, death of the patient or the end of the year 2002. The 10-year survival was 77.6% for the Romanus cup and 49.1% for the TTAP-ST cup. In contrast to these inadequate outcomes, the cementless Bi-Metric stem yielded excellent results with a survival rate of 100% for aseptic loosening during a mean follow-up period of 10 years.
对55例青少年慢性关节炎患者使用双尺寸股骨柄和两种髋臼组件进行的77例非骨水泥型全髋关节置换术的生存率进行了分析。这些患者在1986年至1996年间接受治疗。他们发病时的平均年龄为8.0岁,手术时的平均年龄为28.1岁。平均随访期为9.6年。术后3个月以及1、4、8、12和16年进行随访评估。生存分析的终点是翻修手术、患者死亡或2002年底。Romanus髋臼杯的10年生存率为77.6%,TTAP-ST髋臼杯的10年生存率为49.1%。与这些不理想的结果形成对比的是,非骨水泥双尺寸股骨柄取得了优异的结果,在平均10年的随访期内无菌性松动的生存率为100%。
