中文摘要: 目的 探讨基于MRI的移动性脊髓线(mSC-line)评估体系对多节段脊髓型颈椎病(MCSM)后路单开门手术的临床决策价值。方法 采用回顾性队列研究设计,纳入2022年1月至2024年6月东南大学附属南通市第一民医院收治的MCSM患者138例,通过个体化设计开门节段使所有病例MRI上均达到mSC-line阳性标准。比较总体及不同亚组(K-line阳性与K-line阴性、Ⅰ型与Ⅱ/Ⅲ型)患者手术前后影像学指标[Cobb角、颈椎曲度指数(CCI)、移动性脊髓线-侵入距离(mSC-INT)]和临床预后指标[日本骨科协会(JOA)评分和颈椎功能障碍指数(NDI)评分]。结果 所有患者JOA评分由术前的10.77±3.91改善至14.25±2.08(P<0.01),NDI评分由21.69±7.04降至6.21±2.66(P<0.01)。脊髓压迫参数mSC-INT均显著变大。K-line阴性组(n=73)与K-line阳性组(n=65)术后JOA评分差异无统计学意义[(14.38±2.12)vs (14.10±2.04),P>0.05]。Ⅰ型组(n=50)与Ⅱ/Ⅲ型组(n=88)术后JOA评分分别为(14.12±2.21)和(14.32±2.00),差异无统计学意义(P>0.05)。结论 基于常规MRI的mSC-line评估体系从诊断工具提升为手术规划依据,突破传统K-line和SC-line分型限制,可为MCSM后路手术提供新的决策依据,推动MCSM外科治疗向精准化、个体化方向发展。
Abstract:Objective To investigate the value of the MRI-based mobile spinal cord line(mSC-line)evaluation system in clinical decision-making for posterior single-door laminoplasty in patients with multilevel cervical spondylotic myelopathy(MCSM). Methods A retrospective cohort study was conducted,including 138 MCSM patients admitted to the Southeast University Affiliated Nantong First People’s Hospital between January 2022 and June 2024. The open-door segments were individually designed so that all cases met the mSC-line(+)criterion on MRI. Imaging parameters[Cobb angle,cervical curvature index(CCI),mobile spinal cord line - intrusion distance(mSC-INT)]and clinical outcomes[Japanese Orthopaedic Association(JOA)score and Neck Disability Index(NDI)score]were compared before and after surgery for the overall cohort and different subgroups[K-line(+)vsK-line(-),TypeIvsType Ⅱ/Ⅲ].Results The JOA score improved significantly from 10.77±3.91 preoperatively to 14.25±2.08 postoperatively(P<0.01),and the NDI score decreased significantly from 21.69 ± 7.04 to 6.21 ± 2.66(P<0.01). The spinal cord compression parameter mSC - INT significantly increased in all patients. There was no statistically significant difference in postoperative JOA score between the K-line(-)group(n=73)and the K-line(+)group(n=65)[(14.38±2.12)vs(14.10±2.04),P>0.05].The postoperative JOA score of the Type Ⅰ group(n=50)and the Type Ⅱ/Ⅲ group(n=88)were(14.12±2.21)and(14.32±2.00),respectively,showing no statistically significant difference(P>0.05). Conclusion The conventional MRI-based mSC-line evaluation system evolves from a diagnostic tool to a basis for surgical planning. It overcomes the limitations of traditional K-line and SC-line classifications,can provide a new basis for decision-making in posterior surgery for MCSM,and promote the advancement of MCSM surgical treatment towards precision and individualization.
