Summary
Surgical disc replacement offers potential long-term benefits over spinal fusion for degenerative low-back conditions. However, due to limited long-term data and potential complications, disc prostheses should be considered experimental.
Area of Science:
- Orthopedics
- Neurosurgery
- Biomedical Engineering
Context:
- Degenerative low-back conditions often require surgical intervention, with spinal fusion (spondylodesis) being a common but unpredictable treatment.
- New disc replacement prostheses have emerged as an alternative to fusion, aiming to prevent adjacent segment degeneration.
Purpose:
- To evaluate the current understanding and recommendations regarding the use of artificial disc prostheses as an alternative to spinal fusion for degenerative low-back conditions.
- To highlight the need for further research into the long-term efficacy and safety of disc replacement surgery.
Summary:
- Short-term results of disc replacement appear comparable to spinal fusion, but this technique requires a more extensive surgical approach, potentially leading to more serious complications.
- Long-term complications are a concern, especially since disc prostheses are often implanted in younger, active patients.
- Despite years of use, reliable middle and long-term data on disc prosthesis performance remain scarce in peer-reviewed literature.
Impact:
- Disc replacement surgery for degenerative low-back conditions should be viewed as experimental and limited to clinical trials.
- Centers performing these procedures must possess extensive experience in spine surgery and the infrastructure for long-term, scientifically rigorous patient follow-up.
- Specialized expertise is crucial for managing potential complications associated with disc prostheses.
