Lumbar Total Disc Replacement and Degenerative Disc Disease
Summary
Degenerative disc disease of the lumbar spine arises from progressive breakdown of intervertebral discs, leading to chronic low back pain, reduced mobility and potential nerve compression. Traditional management has relied heavily on spinal fusion, which, while effective in stabilising the segment, may accelerate adjacent-segment degeneration and limit physiological motion. Lumbar total disc replacement (TDR) has emerged as an alternative surgical intervention that aims to preserve segmental kinematics by substituting the diseased disc with an artificial prosthesis. Modern devices are designed to mimic natural disc geometry, shock absorption and load distribution, thereby restoring disc height, maintaining lordosis and reducing adjacent-joint stress. Patient selection is critical, encompassing single-level disease, intact facet joints and absence of significant instability or deformity. Clinical outcomes are generally reported in terms of pain relief, functional improvement and implant survival, with reoperation rates influenced by factors such as implant positioning, subsidence and heterotopic ossification. Advances in biomaterials, surface coatings and viscoelastic core designs seek to enhance biocompatibility and long-term performance. Although long-term comparative data with fusion remain limited, TDR offers a promising motion-preserving solution for carefully selected patients with symptomatic lumbar degenerative disc disease.

Lumbar Total Disc Replacement and Degenerative Disc Disease publication trend
The graph below shows the total number of articles in lumbar total disc replacement and degenerative disc disease across all publications each year (not limited to Nature Index journals).
Technical terms
Total disc replacement (TDR): Surgical implantation of an artificial intervertebral disc to preserve motion at a degenerative lumbar segment.
Degenerative disc disease (DDD): Age-related deterioration of intervertebral disc structure, causing pain and functional impairment.
Subsidence: Downward migration of the implant into adjacent vertebral bone, compromising disc height and segmental kinematics.
Oswestry Disability Index (ODI): Patient-reported questionnaire measuring degree of disability from low back pain.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
