Instability after total hip arthroplasty (THA) can be a problematic complication and remains one of the leading causes of revision surgery in the early post-operative period. Dual mobility (DM) implants decrease dislocation risk after THA but they come with their own set of complications. Selective use of DM implants for THA in high risk groups can confer the advantages of this construct while mitigating the risks. In this paper, we review the current literature to examine the evidence for or against use of DM implants in various clinical scenarios and provide an algorithm for when to consider using DM design construct in THA.
全髋关节置换术(THA)后的不稳定可能是一个棘手的并发症,并且仍然是术后早期翻修手术的主要原因之一。双动(DM)植入物可降低THA后的脱位风险,但它们也有自身的一系列并发症。在高危人群中选择性使用DM植入物进行THA可以在降低风险的同时赋予这种结构的优势。在本文中,我们回顾了当前的文献,以研究在各种临床情况下支持或反对使用DM植入物的证据,并提供一个算法,用于确定何时考虑在THA中使用DM设计结构。
