摘要

我们提出了第一例记录的聚乙烯衬垫骨折在原发性双活动杯（DMC）全髋关节置换术导致假体内脱位。一位患有髋关节发育不良和腿长不一致病史的50岁女性接受了DMC的原发性全髋关节置换术。她表现为髋关节前侧假体内脱位。翻修手术显示高度交联聚乙烯衬垫骨折。取出衬垫和碎片，植入新的衬垫。这个案例强调了高交联聚乙烯在DMC结构中的潜在机械限制。

Fracture of Dual-Mobility Polyethylene Liner in a Primary Total Hip Arthroplasty: A New Complication to a Modern Design: A Case Report

We present the first documented case of polyethylene liner fracture in a primary dual-mobility cup (DMC) total hip arthroplasty leading to intraprosthetic dislocation. A 50-year-old female with a history of hip dysplasia and leg length discrepancy underwent primary total hip arthroplasty with a DMC. She presented with an anterior intraprosthetic hip dislocation. Revision surgery revealed a fractured highly cross-linked polyethylene liner. The liner and fragments were removed and a new liner was implanted. This case underscores the potential mechanical limitations of highly cross-linked polyethylene in DMC configurations.

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.
