Summary
The Bryan artificial cervical disc offers a safe alternative to fusion after discectomy, preserving spinal motion and providing immediate pain relief for radiculopathy.
Area of Science:
- Spine surgery innovations
- Biomechanical restoration of spinal function
- Minimally invasive cervical disc replacement
Background:
- Anterior cervical discectomy and fusion can accelerate adjacent segment degeneration.
- Artificial cervical disc implantation aims to maintain spinal unit functionality.
- The Bryan Cervical Disc System offers a potential alternative for cervical disc herniation.
Observation:
- Two male patients with C6 radiculopathy due to C5-C6 disc herniation were treated.
- Pre-operative imaging showed preserved motion at the affected cervical levels.
- The Bryan disc was implanted following anterior cervical decompression without fixation.
Findings:
- The procedure was straightforward with no intraoperative or postoperative complications.
- Both patients experienced immediate resolution of radicular pain and rapid discharge.
- Nine-month follow-up confirmed sustained symptom relief and preserved motion.
Implications:
- The Bryan artificial cervical disc appears safe and effective for single-level cervical disc herniation.
- This approach may prevent adjacent segment degeneration associated with fusion.
- Further long-term studies are necessary to confirm safety and efficacy.
