Summary
Cervical disc prostheses may prevent adjacent segment degeneration after anterior cervical discectomy. Early results show good pain relief, but long-term mobility requires further study.
Area of Science:
- Spine surgery
- Biomechanical engineering
- Orthopedic research
Context:
- Anterior cervical discectomy and fusion can lead to adjacent segment degeneration.
- This degeneration occurs in 92% of cases, with clinical symptoms in 25.6% within 10 years.
- Cervical disc prostheses offer a potential solution to preserve motion and prevent degeneration.
Purpose:
- To evaluate the safety and efficacy of the Bryan cervical disc prosthesis.
- To assess clinical outcomes and radiological mobility after implantation.
- To compare prosthesis implantation with traditional anterior cervical discectomy and fusion.
Summary:
- Eight patients received 9 Bryan prostheses for disc degeneration or herniation/spondylosis.
- Post-operative follow-up included dynamic X-rays and the Odom questionnaire.
- Mean follow-up was 12 months, with good radicular pain resolution and prosthesis mobility of 8.9 degrees.
Impact:
- The Bryan prosthesis demonstrated promising short-term pain relief.
- One case of implant fusion occurred at 6 months.
- Long-term mobility and patient selection are crucial for definitive evaluation.
