Ceramic bearing surfaces are increasingly used for total hip replacement, notwithstanding that concern is still related to ceramic brittleness and its possible mechanical failure. The aim of this systematic review is to answer three questions: (1) Are there risk factors for ceramic component fracture following total hip replacement? (2) Is it possible to perform an early diagnosis of ceramic component failure before catastrophic fracture occurs? (3) Is it possible to draw guidelines for revision surgery after ceramic components failure? A PubMed and Google Scholar search was performed and reference citations from publications identified in the literature search were reviewed. The use of 28 mm short-neck femoral head carries an increased risk of fracture. Acetabular component malposition might increase the risk of ceramic liner fractures. Synovial fluid microanalysis and CT scan are promising in early diagnosis of ceramic head and liner failure. Early revision is suggested in case of component failure; no consensus exists about the better coupling for revision surgery. Ceramic brittleness remains a major concern. Due to the increased number of ceramic on ceramic implants, more revision surgeries and reports on ceramic components failure are expected in the future. An algorithm of diagnosis and treatment for ceramic hip failure is proposed.
陶瓷轴承表面越来越多地用于全髋关节置换,尽管仍然存在与陶瓷脆性及其可能的机械故障相关的担忧。本系统评价旨在回答三个问题:(1)全髋关节置换后陶瓷部件骨折是否存在危险因素?(2)是否有可能在灾难性骨折发生之前对陶瓷部件故障进行早期诊断?(3)是否有可能为陶瓷部件故障后的翻修手术制定指南?进行了 PubMed 和 Google Scholar 搜索,并对文献检索中确定的出版物的参考文献进行了审查。使用 28 毫米短颈股骨头会增加骨折的风险。髋臼部件位置不当可能会增加陶瓷衬里骨折的风险。关节液微分析和 CT 扫描在早期诊断陶瓷头和衬里故障方面具有很大的前景。一旦出现部件故障,建议尽早进行翻修;对于翻修手术更好的结合,目前还没有共识。陶瓷脆性仍然是一个主要关注点。由于陶瓷-陶瓷植入物的数量增加,预计未来会有更多的翻修手术和关于陶瓷部件故障的报告。提出了一种用于诊断和治疗陶瓷髋关节故障的算法。
