Abstract

This case series reports the only 3 instances of ceramic liner breakage among patients who underwent total hip arthroplasty (THA) with polyethylene–ceramic composite (sandwich-type) liners at our center between 1999 and 2002. Breakages occurred at approximately 6 (n = 2) and 17 years (n = 1) after the primary THA. Symptoms included audible crepitation, pain, and restricted motion during normal activities. Surgical revisions utilized a polyethylene liner and third-generation alumina ceramic head, with synovectomy and irrigation to remove debris (preventing third-body wear). All patients achieved good long-term outcomes. Although infrequent, the risk of breakage increases over time, and several patients still carry these liners years after THA. This case series underscores the importance of vigilant follow-up, patient education, and timely intervention to manage this infrequent but potentially catastrophic complication.

聚乙烯-陶瓷复合材料（三明治型）衬垫破裂的处理和结果：来自长期随访的经验教训

本病例系列报告了1999年至2002年间在本中心接受聚乙烯-陶瓷复合（三明治型）衬垫全髋关节置换术（THA）的患者中仅有的3例陶瓷衬垫破裂的病例。骨折发生在原发性THA后约6年（n = 2）和17年（n = 1）。症状包括可听到的震颤、疼痛和正常活动时的运动受限。手术修复使用聚乙烯衬垫和第三代氧化铝陶瓷头，并用滑膜切除术和冲洗去除碎片（防止第三体磨损）。所有患者均获得良好的长期预后。虽然不常见，但随着时间的推移，破裂的风险增加，一些患者在THA后数年仍携带这些衬垫。这一系列病例强调了警惕随访、患者教育和及时干预的重要性，以管理这种不常见但潜在的灾难性并发症。

期刊介绍： Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
