导言：双活动杯(DMC)的概念是由吉尔斯·布斯奎特教授于1974年提出的。它的目的是防止术后脱位，恢复髋关节的生理活动范围，并减少界面处的应力。自创建以来，该设计经过多次修改，以减少并发症发生率，提高植入物存活率，并扩大适应证。涉及的领域：本综述的目的是根据其40年的历史讨论该植入物的优点和缺点，并根据已发表的结果提出一系列适应症。这将为外科医生提供对DMC的完整概述。专家评论：发表的关于DMC的研究证实了低脱位率。DMC加班的改进大大减少了与磨损相关的并发症，如无菌性松动和假体内脱位(IPD)。根据文献，适应症已经扩大，不再局限于翻修手术。在我们得出正式结论并巩固这些有希望的成果之前，需要进行长期的研究。
Introduction: The dual mobility cup (DMC) concept was proposed by Professor Gilles Bousquet in 1974. Its' aims were to prevent postoperative dislocation, restore the physiological range of motion of the hip, and reduce the stresses at the interface. Since it was created, this design has been modified multiple times to reduce the complication rate, improve implant survival, and expand the indications. Areas covered: The objective of this review is to discuss the advantages and disadvantages of this implant based on its 40-year history and also to propose a range of indications based on published results. This will provide surgeons with a complete overview of DMC. Expert commentary: Published studies on DMC confirm the low dislocation rate. Improvements made to DMC overtime have greatly reduced the complications related to wear, such as aseptic loosening and intraprosthetic dislocation (IPD). According to the literature, the indications have expanded and are no longer limited to revision surgery only. Long-term studies are needed before we can draw formal conclusions and consolidate these promising results.
