We reviewed 81 consecutive ABG I primary total hip replacements implanted in 72 patients between January 1993 and December 1998. The mean follow-up was 8.2 (range 7-12) years. There was significant polyethylene wear and osteolysis associated with the acetabular cup . The cumulative survival of the cup with revision being the end point at 8.2 years was 95.1% (95% CI: 92-97.6%). However, the cumulative survival of the cup with revision and aseptic loosening together was 72% (95% CI: 61-78%) and survival of the acetabular liner for wear was 62% (95% CI: 48-74%). Stem survival with revision being the end point was 100%. In spite of significant radiological failures of the cups, most patients remained asymptomatic. Though results of the ABG stems in this series were good, we advocate a regular follow-up of all these hips in view of the poor outcome of the cups.
我们回顾了1993年1月至1998年12月期间为72例患者植入的81例连续ABG I型初次全髋关节置换术。平均随访时间为8.2年（范围7 - 12年）。髋臼杯存在显著的聚乙烯磨损和骨溶解。以翻修为终点的髋臼杯在8.2年时的累积生存率为95.1%（95%可信区间：92 - 97.6%）。然而，以翻修和无菌性松动共同作为终点的髋臼杯累积生存率为72%（95%可信区间：61 - 78%），髋臼内衬因磨损的生存率为62%（95%可信区间：48 - 74%）。以翻修为终点的股骨柄生存率为100%。尽管髋臼杯存在显著的影像学失败，但大多数患者仍无症状。尽管该系列中ABG股骨柄的结果良好，但鉴于髋臼杯的不良结局，我们主张对所有这些髋关节进行定期随访。
