Objective: To study the correlation between preoperative cervical curvature and clinical outcomes of chronic multilevel cervical spondylotic myelopathy patients after expansive open-door laminoplasty, and to provide a certain basis for judging the prognostic outcomes of patients. Methods: Ninety-four patients who were treated with ttitanium plate-supported expansive open-door laminoplasty for chronic cervical spondylotic myelopathy at our hospital from January 2015 to December 2022 were selected. Based on the results of preoperative radiographs, patients were categorized into the groups A (n = 26), B (n = 25) and C (n = 43) using the Cobb angle of the cervical spine as the criterion. The spinal cord posterior displacement distance at each level of laminoplasty (C3~C7) was measured and calculated through the midsagittal images of MRI T2-weighted. Statistic analysis was performed to analyze the difference of spinal cord posterior displacement distance at each level (C3~C7) among three groups. Neurologic function (JOA score) was evaluated preoperatively and at the final follow-up, and the improvement rate of JOA score at the final follow-up was calculated and compared between the three groups. Results: There was no statistical difference in age, gender, disease duration, and preoperative JOA score between the three groups (P > 0.05). There was significant posterior displacement of the spinal cord in all segments of C3~C7 in three groups, but there was no statistically significant difference in the distance of posterior displacement of the spinal cord (p > 0.05). The average JOA improvement rates at the last follow-up of the three groups were 53.22%, 57.30% and 50%, respectively, with no statistically significant difference (P > 0.05). There was no linear correlation between the spinal cord posterior displacement distance at the C5 level and the duration of the patient's disease and the JOA improvement rate at the last %K 多节段脊髓型颈椎病， %K 单开门椎管扩大成形术， %K 颈椎曲度， %K 危险因素， %K 疗效
