The dual mobility cup (DMC) is an increasingly important tool not only in primary but also in revision total hip arthroplasty to prevent dislocation and eventually reduce postoperative complication rates. Various studies have shown survival rates with DMCs of up to 100% with an average dislocation rate of less than 1.5% after primary hip arthroplasty and a follow-up of 10 years. In revision surgery, survival rates of up to 99% were reported with dislocation rates between 0 and 10% after an average of 5 years after implantation. This article is intended to provide an overview of the principle and function of DMCs. Furthermore, indications as well as complications are presented.
双活动臼杯（DMC）不仅在初次全髋关节置换术中，而且在翻修全髋关节置换术中都是一种越来越重要的工具，用于防止脱位并最终降低术后并发症发生率。各种研究表明，初次髋关节置换术后使用DMC的10年生存率高达100%，平均脱位率低于1.5%。在翻修手术中，植入后平均5年的生存率高达99%，脱位率在0%至10%之间。本文旨在概述DMC的原理和功能。此外，还介绍了其适应证和并发症。
