In Patients with Cervical Radiculopathy, Arthroplasty and Fusion Surgical Treatment Did Not Differ for Disability at 5 Years

Levels [EQ-5D-3L]), arm pain and neck pain, reoperations, and adjacent segment dis- ease). 146 patients were needed to detect a minimal clinically important 10-point differencein NDI (80% power, 2-sided a = 0.05) between groups, assuming a standard deviation of 18 points and 40% loss to follow-up. Main results: The arthroplasty and fusion group groups did not differ for NDI, EQ-5D-3L, arm pain, or neck pain (Table I), or for reoperations (15% vs. 12%, p = 0.61) or adjacentsegmentdisease(0%vs.1.5%,p = 0.32)at5years. Conclusion: In patients with cervical radiculopathy, arthroplasty and fusion did not differ for disability, quality of life, or pain at 5 years.
