Cervical Disc Replacement Demonstrates Sustained Improvement in International Real-World Study .

Can cervical disc replacement preserve motion while improving spinal alignment? Synergy Spine Solutions reported findings from the PERFORM study involving 120 patients across 5 international clinical sites. Mean Neck Disability Index scores improved from 43.4 before surgery to 7.8 at 2 years, while neck pain scores decreased from 5.8 to 0.8. No device-related adverse events or explantations were reported during available follow-up. These findings support further evaluation of the Synergy Disc, although the nonrandomized design limits conclusions regarding superiority over other cervical disc replacements or fusion.
