New treatment option for Radiculopathy, Cervical
Official title Pilot Study of ZetaFuse™ Bone Graft for the Treatment of Cervical Degenerative Disc Disease
ClinicalTrials.gov ID: NCT05971329
What this study is testing
- What it's testing
- The goal of this pilot clinical trial is to test the safety and preliminary performance of the ZetaFuse Bone Graft in patient requiring fusion of the C3-C7 vertebral bones due to pain or loss of neurological function. Participants will be treated with ZetaFuse during surgical intervention to reduce pain and the loss of neurological function.
