Summary
This study reports the first two-level cervical disc arthroplasty using Bryan disc prostheses for spinal cord compression. This innovative approach may offer a solution for multilevel cervical issues while preserving motion.
Area of Science:
- Neurosurgery
- Spinal Surgery
Background:
- Myeloradiculopathy often results from multilevel cervical spinal cord compression.
- Traditional surgical interventions may involve fusion, potentially leading to adjacent segment disease.
Observation:
- A 49-year-old woman presented with myeloradiculopathy due to two-level spinal cord compression at C5-6 and C6-7.
- She underwent anterior cervical decompression and placement of two Bryan disc prostheses.
Findings:
- This case represents the first reported instance of two-level cervical arthroplasty using the Bryan disc prosthesis.
- The procedure was performed for C5-6 and C6-7 spinal cord compression.
Implications:
- This technique offers a potential alternative for managing multilevel cervical cord compression.
- It may preserve cervical motion and avoid complications associated with bone grafting and fusion.
- Further research could explore its efficacy in reducing adjacent segment disease.
