We have examined retrospectively the correlation between linear wear of the polyethylene socket and calcar height loss (osteolysis) in 266 patients with 410 total hip arthroplasties who were followed up for a minimum of 10 years. A positive correlation existed between wear and osteolysis. The correlation was stronger in patients with osteoarthrosis. Simultaneous bilateral hip arthroplasty showed no difference in the relationship between polyethylene wear and calcar height loss when comparing the right and left hip. There was poor correlation between calcar height loss and wear in patients with rheumatoid arthritis. Our findings support the theory that femoral osteolysis in the total hip arthroplasty is related to the amount of liberated particles generated by the wear of components. The poor correlation found in cases with rheumatoid arthritis could be related to suppression of the immune response in these patients.
我们回顾性研究了266例接受410次全髋关节置换术且至少随访10年的患者中，聚乙烯髋臼杯的线性磨损与股骨距高度丢失（骨质溶解）之间的相关性。磨损与骨质溶解之间存在正相关。在骨关节炎患者中这种相关性更强。同时进行双侧髋关节置换术时，比较左右髋关节，聚乙烯磨损与股骨距高度丢失之间的关系无差异。类风湿关节炎患者的股骨距高度丢失与磨损之间相关性较差。我们的研究结果支持以下理论：全髋关节置换术中股骨骨质溶解与假体磨损产生的游离颗粒量有关。在类风湿关节炎病例中发现的相关性较差可能与这些患者的免疫反应受到抑制有关。
