Artificial disc replacement and fusion in cervical degenerative disc disease and radiculopathy

Takeaway

  • There were no significant clinical or radiographic benefits of artificial disc replacement (ADR) compared with fusion surgery after 5 years in people with cervical degenerative disc disease and radiculopathy.

Why this matters

  • Use of ADR has been recommended on the basis of reduced progression to adjacent-segment pathology (ASP) but this is not supported by these results.
