Comparison of Cervical Sagittal Parameters among Patients with Neck Pain and Patients with Cervical Spondylotic Radiculopathy and Cervical Spondylotic Myelopathy

Objective Previous studies have shown that cervical sagittal alignment is strongly associated with cervical deformity, myelopathy, and cervical adjacent‐segmental disease, and these cervical sagittal parameters are correlated with health‐related quality of life. However, less attention has been paid to cervical sagittal balance in various cervical disorders. This study aimed to compare cervical sagittal parameters between patients with nonspecific neck pain (NS‐NP) and patients with cervical spondylotic radiculopathy (CSR) and cervical spondylotic myelopathy (CSM). Methods We retrospectively examined 236 patients from between January 2020 and October 2022. We divided them into three groups (NS‐NP, CSR, and CSM) and collected general information and cervical sagittal parameters for these patients. The variation of parameters between the size of these parameters and gender differences was analyzed. Pearson's or Spearman's correlation was applied to analyze the association of cervical sagittal parameters of all patients between the three groups. Results There were significant differences in age and sex among the three groups (p
