球窝型人工腰椎间盘假体研究现状

A review on the current state of ball-on-socket type artificial lumbar disc 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。

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.
