In metal-on-polyethylene (MoP) total hip arthroplasty (THA), large metal femoral heads have been used to increase stability and reduce the risk of dislocation. The increased size of the femoral head can, however, lead to increased taper corrosion, with the release of metal ions and adverse reactions. The aim of this study was to investigate the relationship between the size of the femoral head and the levels of metal ions in the blood in these patients.

股骨头的大小不影响金属-聚乙烯全髋关节置换术后的金属离子水平：随机对照试验的五年报告。

在金属对聚乙烯 (MoP) 全髋关节置换术 (THA) 中，使用大型金属股骨头来提高稳定性并降低脱位风险。然而，股骨头尺寸的增加会导致锥度腐蚀加剧，并释放金属离子和不良反应。本研究的目的是调查这些患者股骨头的大小与血液中金属离子水平之间的关系。
