Zirconia ball heads have been implanted successfully from the late 1980s, but reports of wear and fractures have raised concerns about this ceramic biomaterial. This paper reviews the literature on clinical wear of zirconia-polyethylene bearings, zirconia head degradation and fractures, analysing the different factors that have led to clinical failure, such as material source, manufacturing process and type of polyethylene. The results underline the need for more homogeneous clinical series. Careful follow-up of patients with zirconia-polyethylene bearings is recommended.
自20世纪80年代末以来，氧化锆球头已成功植入，但关于磨损和骨折的报告引发了对这种陶瓷生物材料的担忧。本文回顾了有关氧化锆-聚乙烯轴承临床磨损、氧化锆球头降解和骨折的文献，分析了导致临床失败的不同因素，如材料来源、制造工艺和聚乙烯类型。结果强调了需要更具同质性的临床系列研究。建议对使用氧化锆-聚乙烯轴承的患者进行仔细随访。
