It is unclear whether treating only potentially symptomatic levels could provide equivalent results to managing all pathologic levels. Methods: This was a retrospective cohort study of 188 patients undergoing ACDF for degenerative cervical radiculopathy between 2014 and 2020. Patients were divided into two groups: those with all symptomatic levels decompressed (No-FS group, n=162) and those with untreated FS at levels not targeted in surgery (FS group, n=26) . Postoperative outcomes, including neck pain, arm pain, and Neck Disability Index (NDI), were evaluated at 3 months and 2 years. Radiographic parameters and ASD incidence were also compared between groups.  \nResults: Both groups showed significant improvement in neck pain, arm pain, and NDI postoperatively, with no significant intergroup differences at 3 months and 2 years. C2–C7 lordosis and sagittal vertical axis showed similar improvement in both groups postoperatively.
