Summary
Cervical disc replacement offers an alternative to fusion for degenerative disc disease. This case highlights a rare complication: spinal cord compression from Mobi-C disc nucleus migration.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical disc replacement is a surgical option for degenerative cervical spine conditions.
- It serves as an alternative to traditional anterior cervical discectomy and fusion (ACDF).
Observation:
- A patient experienced worsening symptoms of spinal cord compression.
- The compression was attributed to the nucleus of a Mobi-C total disc replacement device.
Findings:
- This is the first reported instance of nucleus migration from a Mobi-C device.
- The migrated nucleus caused significant, symptomatic spinal cord compression.
Implications:
- Highlights a potential, albeit rare, complication of Mobi-C total disc replacement.
- Suggests the need for vigilance regarding device integrity and potential nucleus migration.
- Informs surgical considerations and patient selection for cervical disc replacement procedures.
