背景：双动性（DM）已被证明可以降低全髋关节置换术（THA）后脱位的风险。在过去十年中，引入了组配式DM（modDM）结构，以允许DM关节与标准非骨水泥型髋臼杯配合使用。然而，modDM有效性的临床证据在初次THA中仍然较低，并且对植入物相关并发症的担忧正在增加。这项回顾性比较多中心研究旨在研究与标准关节面（SB）相比，modDM是否可以降低初次THA后的脱位率。研究方法：2017年至2019年期间，使用SB（129例髋关节）或modDM（133例）与相同的非骨水泥型高多孔组配式髋臼杯进行了262例THA。记录脱位、并发症和翻修，并分析植入物存活率。结果如下：平均随访2.5年时，SB组中4例髋关节（3.1%）发生脱位，modDM组中2例髋关节（1.5%）发生假体内脱位（p = 0.44）。SB和modDM患者4年随访时因脱位翻修的植入物存活率分别为95.2%和95.9%（p = 0.50）。结论：与SB相比，在初次THA中使用modDM可能会降低脱位率，即使是在高风险患者中，但是，由于特定的假体内脱位，建议谨慎使用。
Background: Dual mobility (DM) has been proven to reduce dislocation risk after total hip arthroplasty (THA). In the last decade modular DM (modDM) constructs have been introduced to allow the use of DM articulation with standard cementless acetabular shells. However, clinical evidence of modDM effectiveness is still low in primary THA and concerns about implant-related complications are increasing. This retrospective comparative multicenter study is aimed to investigate if the dislocation rate after primary THA could be reduced with modDM in comparison to standard bearing (SB). Methods: 262 THAs were performed between 2017 and 2019, using SB (129 hips) or modDM (133) with the same cementless highly porous modular acetabular cup. Dislocations, complications and revisions were recorded and implant survival was analyzed. Results: At 2.5-year mean follow-up, dislocation occurred in 4 hips (3.1%) within the SB group while intraprosthetic dislocation in 2 hips (1.5%) within the modDM group (p = 0.44). Implant survivals with revision due to dislocation were 95.2% and 95.9% at 4-year follow-up for SB and modDM, respectively (p = 0.50). Conclusions: modDM used in primary THA might reduce dislocation rate in comparison to SB, even in high-risk patients, however, caution is advocated due to specific intraprosthetic dislocation.
