With dislocation being one of the most serious complications of total hip arthroplasty, prevention of recurrent instability has been the driving force behind several implant designs, including large-diameter heads, metal-on-metal bearing surfaces, and constrained acetabular components. Dual-articulation acetabular component design was similarly conceived in an effort to reduce postoperative dislocation risk. This design, developed in France in 1975 and popularized in Europe, was recently approved in the United States and represents a new surgical option for United States orthopedic surgeons performing total hip arthroplasty. In this article, we review the dual-articulation design in terms of its history, biomechanical concepts, published indications, contraindications, outcomes, and complications based on more than 20 years of largely French clinical experience.
脱位是全髋关节置换术最严重的并发症之一，预防反复出现的不稳定一直是多种植入物设计背后的驱动力，这些设计包括大直径股骨头、金属对金属的承重表面以及限制性髋臼组件。双关节髋臼组件设计也是出于降低术后脱位风险的考虑而构思出来的。这种设计于1975年在法国研发并在欧洲推广，最近在美国获得批准，为美国进行全髋关节置换术的骨科医生提供了一种新的手术选择。在本文中，我们基于20多年主要来自法国的临床经验，从双关节设计的历史、生物力学概念、已公布的适应证、禁忌证、疗效及并发症等方面进行综述。
