Total lumbar disc replacement is an alternative to interbody fusion for the effective treatment of symptomatic degenerative disc disease. This paper reviewed the history of ball-on-socket type artificial lumbar disc (ALD) prosthesis, which is a typical ALD prosthesis and summarized the ALD prosthesis research progress, according to different materials such as metal-on-metal, metal-on-polymer, and polymer-on-polymer prosthesis. The structural design factors of ball-on-socket type ALD prosthesis were analyzed and its prospect of development was also presented. The purpose of this paper is to provide a theoretical reference for the design of the ball-on-socket ALD prosthesis by reviewing the current state of ball-on-socket type ALD prosthesis.
人工腰椎间盘置换术是治疗椎间盘退行性病变、缓解腰背痛的有效方式。球窝型人工腰椎间盘是最常用的假体类型。本文回顾了球窝型人工腰椎间盘假体的历史，综述了金属—聚合物、金属—金属和聚合物—聚合物不同组合配副的球窝型人工腰椎间盘假体产品现状。结合最新研究进展，分析球窝型人工腰椎间盘假体结构设计因素及影响，并对球窝型人工腰椎间盘假体未来的发展加以展望，以期为设计球窝型人工腰椎间盘假体提供更加全面系统的理论参考。.
