Each year, approximately 217000 primary total hip arthroplasties (THAs) are performed in the United States (National Center for Health Statistics, 2003). This number is expected to increase as our population ages, and the indication for THA expands to younger and more active patients. Efforts are continually being made to improve implant design and, ultimately, patient outcomes. One area in particular that has undergone tremendous change is bearing surface technology. Ceramic-on-ceramic technology has gained widespread popularity in young patients because of its improved wear characteristics and durability. Bearing surface advancement must be tempered with analysis of implant-specific complications. We report a case of an audible hip complication after the use of ceramic components in THA.
在美国，每年大约进行217000例初次全髋关节置换术（THA）（美国国家卫生统计中心，2003年）。随着我国人口老龄化，预计这一数字还会增加，而且THA的适应证扩展到了更年轻、活动更多的患者。人们不断努力改进植入物设计，最终改善患者的治疗效果。特别是承重面技术领域发生了巨大变化。由于其改善的磨损特性和耐用性，陶瓷对陶瓷技术在年轻患者中广受欢迎。承重面技术的进步必须结合对特定植入物并发症的分析。我们报告了1例在THA中使用陶瓷部件后出现可闻及的髋关节并发症的病例。
