Acetabular bone loss, and specifically when it is associated with a chronic pelvic discontinuity, presents a difficult clinical challenge at the time of revision total hip arthroplasty. Most centers have advocated the use of noncemented constructs in an effort to achieve biologic fixation. The authors prefer noncemented fixation with use of the acetabular distraction technique in conjunction with modular porous metal augments for the treatment of severe acetabular bone loss and an associated chronic pelvic discontinuity.
髋臼骨缺损，尤其是当它与慢性骨盆连续性中断相关时，在翻修全髋关节置换术时会带来棘手的临床挑战。大多数中心主张使用非骨水泥固定结构以实现生物学固定。作者更倾向于采用髋臼撑开技术结合模块化多孔金属增强物进行非骨水泥固定，用于治疗严重的髋臼骨缺损及相关的慢性骨盆连续性中断。
