Spinal fusion for degenerative disc disease has risks. Artificial disc research aims to improve treatments, but outcomes are variable, necessitating further study for better patient results.
Area of Science:
- Spine surgery
- Biomedical engineering
- Orthopedics
Background:
- Spinal fusion for degenerative disc disease presents significant side effects, including infection and adjacent segment degeneration.
- The development of artificial disc prostheses is inspired by successful joint replacements, but current designs have limitations.
- Degenerative disc disease progresses through distinct stages: dysfunction, instability, and stabilization.
Purpose of the Study:
- To review the natural history and diagnostic methods for degenerative disc disease.
- To explore anatomical and biomechanical considerations for artificial disc design.
- To evaluate the evolution, design criteria, and clinical outcomes of artificial disc prostheses.
Main Methods:
- Review of clinical and anatomical data on degenerative disc disease progression.
- Analysis of diagnostic tools, including magnetic resonance imaging and discography.
- Examination of proposed design criteria for intervertebral prostheses.
- Evaluation of the evolution and clinical outcomes of total disc and nucleus replacements.
Main Results:
- Discography is the most accurate diagnostic test for identifying the pain-generating disc level.
- Multiple design criteria for ideal intervertebral prostheses have been proposed.
- Artificial disc technology has evolved into total disc replacement and nucleus pulposus replacement.
- Clinical outcomes for current artificial disc replacements remain variable.
Conclusions:
- Further research is needed to improve artificial disc technology and clinical outcomes.
- Understanding the natural history and biomechanics is crucial for designing effective disc prostheses.
- Artificial disc development aims to mitigate the risks associated with spinal fusion for degenerative disc disease.
