Preoperative Cervical Extension Range of Motion and C7 Preservation As Predictors of Axial Symptoms Following Laminoplasty

To identify independent predictors of postoperative axial symptoms (AS) after cervical laminoplasty (CLP) and evaluate the predictive value of preoperative cervical range of motion. We retrospectively reviewed 191 patients with cervical spondylotic myelopathy who underwent unilateral open-door CLP between January 2019 and January 2024. Patients were classified into AS (n=73) and no AS (n=118) groups. Demographic, surgical, radiographic, and clinical variables were compared. Binary logistic regression identified independent predictors, and receiver operating characteristic analysis assessed predictive performance. Compared with the no-AS group, the AS group had higher BMI (26.5±3.7 vs. 25.4±3.3 kg/m2, P=0.027), more frequent T2-weighted spinal cord increased signal intensity (64.4
