BackgroundModic changes (MC) of the vertebral endplates and facet joint degeneration are common causes of neck pain. No previous study has shown the prevalence of and relationship between MC and facet joint changes in cervical spondylotic myelopathy (CSM). The objective of this article was to study the endplate and facet joint changes in CSM.MethodsMagnetic resonance imaging of the cervical spine in 103 patients with CSM was retrospectively evaluated. The scans were evaluated by 2 raters, who classified spinal segments according to the Modic classification and the degree of facet degeneration.ResultsIn patients <50 years old, there were no MC in 61.5%. In patients with MC, Modic type II at C4-C5 was observed most frequently. MC were found in 71.4% of patients ≥50 years old. In patients with MC, Modic type II at C3-C4 was observed most frequently. Degenerative changes of the facet joints were found frequently in both patients <50 years old (77.5%) and patients ≥50 years (90.2%), and grade I degeneration was observed most frequently in both groups. There was a significant correlation between MC and facet joint changes.ConclusionsMC in the cervical spine are common magnetic resonance imaging findings in patients with CSM ≥50 years old. Degenerative facet joint changes are found in the majority of patients with CSM regardless of age. We found a significant correlation between MC and facet joint changes at the same level, indicating that both imaging findings are involved in a common pathophysiological pathway.Copyright © 2023 Elsevier Inc.
