| 目的 探讨椎管扩大椎板成形术联合MRI T2加权像髓内高信号（ISI）节段单侧侧块螺钉内固定治疗多节段脊髓型颈椎病（MCSM）的临床疗效。方法 2015年1月—2019年1月收治伴MRI T2加权像髓内ISI的MCSM患者59例，其中26例采用椎管扩大椎板成形术联合MRI T2加权像髓内ISI节段单侧侧块螺钉内固定治疗（A组），33例采用单纯椎管扩大椎板成形术治疗（B组）。记录2组手术时间、术中出血量及并发症发生情况。采用日本骨科学会（JOA）评分及其改善率评价神经功能状态。在颈椎X线片上测量C2~7 Cobb角，计算颈椎整体活动度（ROM）。测量髓内信号改变比值（SCR=ISI区域光密度值/C7 ~ T1正常区域光密度值），定量评估髓内ISI程度，并进一步分析SCR变化值对JOA评分及其改善率的影响。结果 所有手术顺利完成。2组手术时间、术中出血量差异无统计学意义（P > 0.05）。A组术后JOA评分及其改善率、术后SCR及其变化值明显高于B组，差异均有统计学意义（P < 0.05）。2组术后C2~7 Cobb角、颈椎整体ROM及其保留率差异无统计学意义（P > 0.05）。2组并发症发生率差异无统计学意义（P > 0.05）。SCR变化值显著改变组的JOA评分改善率最高，中度改变组次之，轻度改变组最低，3组间两两相比，JOA评分改善率差异均有统计学意义（P < 0.05）。结论 对于伴MRI T2加权像髓内 ISI的MCSM患者，椎管扩大椎板成形术联合MRI T2加权像髓内ISI节段单侧侧块螺钉内固定具有较好的临床和影像学结果，尤其在术后髓内ISI的改善方面具有一定优势。 |

| Abstract: |
| Objective To investigate the clinical efficacy of expansive laminoplasty combined with unilateral lateral mass screw fixation at MRI T2-weighted intramedullary increased signal intensity（ISI） segment for treatment of multi-segment cervical spondylotic myelopathy（MCSM）. Methods From January 2015 to January 2019，59 patients with MCSM accompanied with MRI T2-weighted intramedullary ISI were admitted. Among them，26 patients underwent laminoplasty combined with unilateral lateral mass screw fixation at MRI T2-weighted intramedullary ISI segment（group A），while 33 underwent laminoplasty alone（group B）. The operation time，intraoperative blood loss and complications were recorded in the 2 groups. The neurological function was evaluated by the Japanese Orthopaedic Association（JOA） score and its improvement rate. C2-7 Cobb angle were measured on roentgenographs，cervical overall range of motion（ROM） was calculated. Signal change ratio（SCR=ISI area optical density value/C7 - T1 normal area optical density value） was measured to evaluate ISI lesion degree. The effect of SCR variation on JOA score and its improvement rate was further analyzed. Results All the operations were completed successfully. There was no significant difference in operation time and intraoperative blood loss between the 2 groups（P > 0.05）. JOA score and its improvement rate，SCR and its change value in group A were significantly higher than those in group B，all with a statistical significance（P < 0.05）. There was no significant difference in C2-7 Cobb angle，cervical ROM and its retention rate between the 2 groups（P > 0.05）. There was no significant difference in the incidence of complications between the 2 groups（P > 0.05）. The improvement rate of JOA score in the obviously changed SCR group was the highest，followed by the moderately changed group，and the mildly changed group was the lowest. Pairwise comparison among the 3 groups showed significant differences in improvement rate of JOA score（P < 0.05）. Conclusion For MCSM patients with MRI T2-weighted intramedullary ISI，laminoplasty combined with unilateral lateral mass screw fixation at MRI T2-weighted intramedullary ISI segment has good clinical and imaging results，especially in improving postoperative intramedullary ISI. |
