Chronic pelvic discontinuity is a distinct and unique challenge seen during revision total hip arthroplasty (THA) in which the superior ilium is separated from the inferior ischiopubic segment through the acetabulum, rendering the anterior and posterior columns discontinuous. The operative management of acetabular bone loss in revision THA is one of the most difficult challenges today. Common treatment options include cage reconstruction with bulk acetabular allograft, custom triflange acetabular component, a cup-cage construct, jumbo acetabular cup with porous metal augments, or acetabular distraction with a porous tantalum shell with or without modular porous augments.
慢性骨盆不连续是翻修全髋关节置换术(THA)过程中出现的一种独特且特殊的挑战,即髂骨通过髋臼与耻骨坐骨下段分离,导致前后柱不连续。翻修THA中髋臼骨缺损的手术处理是当今最具挑战性的难题之一。常见的治疗选择包括使用大块髋臼同种异体骨进行笼状重建、定制三翼髋臼组件、杯笼结构、带多孔金属增强物的超大号髋臼杯,或使用带或不带模块化多孔增强物的多孔钽壳进行髋臼牵张。
