New artificial disc could keep neck moving after surgery
NCT ID NCT00478088
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new artificial disc called NeoDisc against standard fusion surgery (ACDF) in 488 people with a damaged disc in the neck. The goal was to see if NeoDisc is as safe and effective at relieving pain and improving function over two years. Participants were randomly assigned to receive either the artificial disc or fusion, and researchers tracked neck disability, complications, and nerve function.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
NeoDisc artificial disc replacement device
What this could lead to
If successful, NeoDisc could offer a motion-preserving alternative to fusion surgery, potentially reducing long-term neck stiffness and adjacent disc problems.
What could go wrong
This is a completed trial, but results may not apply to all patients. Risks include device failure, need for revision surgery, or no better outcomes than standard fusion.
