The results are presented of 92 double-cup arthroplasties modified in light of previously published experience. The review period lasted up to 7 years after operation. Eighty-six had a metal femoral component and six had a ceramic femoral component. Forty metal femoral cups were matched with a cemented acetabulum, while with 46 the acetabular implant was cementless. The overall revision rate for the metal femoral cups was 23.3%, and a further 31.8% demonstrated radiological signs suggestive of loosening. There was no difference between the cemented and uncemented cups in terms of revision rates or clinical results. The clinical results of those hips that have not yet loosened were excellent. A histological study showed that femoral lossening was associated with an erosive cellular response. Surface arthroplasty of the hip with current materials should be abandoned.
本文展示了根据以往发表的经验进行改良的92例双杯关节成形术的结果。随访期长达术后7年。86例使用金属股骨部件，6例使用陶瓷股骨部件。40个金属股骨杯与骨水泥固定的髋臼相匹配，而46个髋臼植入物为非骨水泥型。金属股骨杯的总体翻修率为23.3%，另有31.8%显示出提示松动的放射学征象。骨水泥固定杯和非骨水泥固定杯在翻修率或临床结果方面没有差异。那些尚未松动的髋关节的临床结果极佳。组织学研究表明，股骨松动与侵蚀性细胞反应有关。应放弃使用当前材料进行髋关节表面置换术。
