人工腰椎间盘假体及手术相关并发症现状分析

Surgical complications related to artificial lumbar disc prosthesis

随着医学的进步及人们对脊柱生理重建的要求不断提高,不同种类的人工腰椎间盘假体也得到蓬勃发展。从第一代Charité假体到第二代ProDisc-L假体,再到目前的第三代Activ-L Systems假体都在临床进行了大量应用,此外还有Acroflex、Maverick、XL TDR、M6-L等其他产品也获得批准应用。本文就人工腰椎间盘假体应用的相关文献进行综合分析,按照非限制型、半限制型、限制型、整体式弹性体、限制型+弹性芯、整体式横向植入等不同的设计特点,将相应假体的并发症进行综述,为后续假体设计改进和应用提供参考。

As a result of medical advancement and increasing requirements for the physiological reconstruction of the spine,various kinds of artificial lumbar prostheses have flourished.The first-generation Charitéprosthesis,the second-generation ProDisc-L prosthesis and the third-generation Activ-L Systems prosthesis have all been applied widely in clinic.In addition,Acroflex,Maverick,XL TDR,M6-L and other products have also been approved for clinical application.This article reviews the literature on application of artificial lumbar intervertebral disc prostheses to conduct a comprehensive analysis of the surgical complications related to the different design features of the prostheses like unconstrained,semiconstrained,constrained,one elastomeric piece,constrained plus elastic core and integral lateral implantation,hoping to provide references for subsequent improvement in design and application of the prosthesis.
