Abstract

Objective: To evaluate the impact of preoperative cervical sagittal parameters on the loss of cervical lordosis (LCL) after expansive open-door laminoplasty (EOLP) and explore the optimal predictors.

Methods: A retrospective analysis was performed on the clinical data of 94 patients with cervical spondylotic myelopathy who underwent EOLP from January 2019 to January 2021, including 61 males and 33 females, aged 34 to 75 years old with an average age of(53.1±9.7) years old. Preoperative routine anteroposterior, lateral, and dynamic X-ray films of the cervical and thoracic spine were taken to comprehensively assess various cervical sagittal parameters: T₁ slope (T₁S), C₂-C₇ sagittal vertical axis (C₂-C₇ SVA), C₂-C₇ cervical lordosis (CL), T1 slope-cervical lordosis (T₁S-CL), cervical lordosis/T₁ slope (CL/T₁S), C₂-C₇ cervical range of motion (ROM), thoracic kyphosis (TK), cephalad vertebral level undergoing laminoplasty (CVLL), and C_2,3 disc angle. Statistical analysis was conducted to identify the independent risk factors of preoperative sagittal parameters for postoperative LCL.

Results: A total of 94 patients meeting the inclusion and exclusion criteria were enrolled, with a postoperative follow-up period of 12 to 24 months. Pearson correlation analysis showed that T₁S, T₁S-CL, CVLL, and C_2,3 disc angle were significantly correlated with postoperative LCL, while C₂-C₇ SVA, CL, CL/T₁S, C₂-C₇ ROM, and TK had no significant correlation with postoperative LCL. Regression analysis further indicated that T₁S (β=0.426, P<0.001), T₁S-CL (β=0.716, P<0.001), C_2,3 disc angle (β=0.351, P<0.001), and CVLL (β=-3.348, P<0.001) were significantly correlated with postoperative LCL.

Conclusion: For patients with cervical spondylotic myelopathy treated with EOLP, T₁S, T₁S-CL, CVLL, and C_2,3 disc angle are important factors for predicting cervical lordosis loss, among which CVLL may be the most critical predictive indicator.

[基于矢状面参数的开放式椎板成形术后颈椎曲度损失的预测]。

目的：评价术前颈椎矢状面参数对开放性椎板成形术（EOLP）后颈椎前凸（LCL）消失的影响，并探讨最佳预测指标。方法：回顾性分析2019年1月至2021年1月行EOLP治疗的94例脊髓型颈椎病患者的临床资料，其中男性61例，女性33例，年龄34 ~ 75岁，平均年龄（53.1±9.7）岁。术前常规取颈椎、胸椎正位、侧位及动态x线片，综合评估各种颈椎矢状面参数：T1坡度（T1S）、C2- c7矢状垂直轴（C2- c7 SVA）、C2- c7颈椎前凸（CL）、T1坡度-颈椎前凸（T1S-CL）、颈椎前凸/T1坡度（CL/T1S）、C2- c7颈椎活动范围（ROM）、胸椎后凸（TK）、行椎板成形术的头侧椎体水平（CVLL）、C2、3椎间盘角度。统计分析术前矢状面参数对术后LCL的独立危险因素。结果：共纳入94例符合纳入和排除标准的患者，术后随访12 ~ 24个月。Pearson相关分析显示，T1S、T1S-CL、CVLL、C2、3椎间盘角度与术后LCL有显著相关性，而C2- c7 SVA、CL、CL/T1S、C2- c7 ROM、TK与术后LCL无显著相关性。进一步回归分析显示，T1S (β=0.426, P1S-CL (β=0.716, P2,3椎间盘角度（β=0.351, ppp）结论：对于EOLP治疗的脊髓型颈椎病患者，T1S, T1S- cl， CVLL和C2,3椎间盘角度是预测颈椎前凸丧失的重要因素，其中CVLL可能是最关键的预测指标。
