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.
本病例系列报告了1999年至2002年间在我们中心接受聚乙烯 - 陶瓷复合材料（三明治型）衬垫全髋关节置换术（THA）的患者中仅有的3例陶瓷衬垫破损情况。破损发生在初次全髋关节置换术后约6年（n = 2）和17年（n = 1）。症状包括在正常活动期间可听到的摩擦音、疼痛和活动受限。手术翻修使用了聚乙烯衬垫和第三代氧化铝陶瓷头，并进行滑膜切除术和冲洗以清除碎片（防止三体磨损）。所有患者均取得了良好的长期疗效。尽管这种情况不常见，但破损风险会随着时间增加，并且一些患者在全髋关节置换术后数年仍带着这些衬垫。本病例系列强调了警惕随访、患者教育以及及时干预以处理这种不常见但可能具有灾难性的并发症的重要性。
