Unauthorized commercial reproduction of this slide is prohibited Supplemental PowerPoint Slides Cervical degenerative spondylolisthesis is common in patients older than 50, who sometimes require surgical treatment due to clinical symptoms. There is no report regarding its natural history. We report a retrospective case series of 27 patients with cervical degenerative spondylolisthesis assessed by neutral and dynamic lateral radiographs of the cervical spine with a mean follow up period of 39.0 months (range, 24-92). None of the anterolistheses or retrolistheses had progressed by the final visit.
