Abstract

Lumbar total disc replacement (LTDR) has emerged as amotion-preserving surgical for treating degenerativedisc disease (DDD). This article reviews the evolution ofLTDR technology with emphasis on advances in devicedesign, biomechanical research, and clinicalperformance. The integration of finite element analysis(FEA) and biomechanics has enabled more preciseoptimization of implant design and material properties.Clinical potential evidence indicates that modern LTDRscan maintain spinal mobility with long-term performanceand personalized models challenges. Future research inbiomimetic materials, and additive manufacturing (AM),and FEA-based optimization is expected to drive the nextgeneration of personalized, durable disc replacementtechnologies.
