Dislocation remains a leading cause of failure following revision total hip arthroplasty (THA). While dual-mobility (DM) bearings have been shown to mitigate this risk, options are limited when retaining or implanting an uncemented shell without modular DM options. In these circumstances, a monoblock DM cup, designed for cementing, can be cemented into an uncemented acetabular shell. The goal of this study was to describe the implant survival, complications, and radiological outcomes of this construct.

非骨水泥翻修髋臼组件中的骨水泥双活动度结构。

脱位仍然是翻修全髋关节置换术 (THA) 失败的主要原因。虽然双移动 (DM) 轴承已被证明可以减轻这种风险，但在没有模块化 DM 选项的情况下保留或植入非骨水泥外壳时，选择受到限制。在这些情况下，设计用于骨水泥固定的整体式 DM 杯可以骨水泥固定到未骨水泥固定的髋臼壳中。本研究的目的是描述该结构的种植体存活率、并发症和放射学结果。
