UNLABELLED
The outcome of a single design of dual mobility cup was prospectively evaluated in a continuous series of 994 revision THAs with respect to dislocation and intra-prosthetic dislocation (IPD). At a 7.3-year mean follow-up, the dislocation rate was 1.5% and the IPD rate was 0.2%. The 2 IPD occurred in acetabular-only revisions and were related to a poor head-to-neck ratio with early impingement and wear at the polyethylene mobile component chamfer. Dual mobility cups demonstrated a low dislocation rate in revision THA but did not compensate for potential perioperative technical errors. In addition, IPD did not appear to be a concern with respect to the benefit in term of instability prevention though caution is advised in acetabular-only revision associated with a poor head-to-neck ratio.

对994例连续的翻修全髋关节置换术（THA）患者，前瞻性评估了单一设计的双动杯在脱位和假体内部脱位（IPD）方面的结果。平均随访7.3年时，脱位率为1.5%，IPD率为0.2%。2例IPD发生在单纯髋臼翻修术中，与头颈比不佳、早期撞击以及聚乙烯活动部件倒角处磨损有关。双动杯在翻修THA中显示出较低的脱位率，但不能弥补潜在的围手术期技术失误。此外，尽管对于仅进行髋臼翻修且头颈比不佳的情况建议谨慎操作，但就预防不稳定的益处而言，IPD似乎不是一个问题。
