ABSTRACT
Lumbar total disc replacement (LTDR) has emerged as a motion-preserving surgical for treating degenerative disc disease (DDD). This article reviews the evolution of LTDR technology with emphasis on advances in device design, biomechanical research, and clinical performance. The integration of finite element analysis (FEA) and biomechanics has enabled more precise optimization of implant design and material properties. Clinical potential evidence indicates that modern LTDRs can maintain spinal mobility with long-term performance and personalized models challenges. Future research in biomimetic materials, and additive manufacturing (AM), and FEA-based optimization is expected to drive the next generation of personalized, durable disc replacement technologies.
