Abstract: ［Abstract］ Objective To observe the effects of anterior cervical corpectomy decompression and titanium mesh-bone graft composite on neck disability index （NDI） score in patients with cervical spondylotic myelopathy. Methods Fifty-six cases of patients with cervical spondylotic myelopathy admitted to our hospital from February 2012 to October 2017 were selected and divided into the control group （n=28） and the observation group （n=28）. The control group was assigned to anterior cervical discectomy and bone grafting internal fixation, and the observation group was given anterior cervical corpectomy decompression and full-contact titanium mesh-bone graft composite, and the patienys were followed up for 6 months. The operative time, intraoperative blood loss, hospital stay and intervertebral height loss were compared between the two groups, and the scores of NDI and Japanese Orthopaedic Association（JOA）were recorded before operation and at 6 months after operation, and the bone grafting fusion rate and postoperative improvement rate were calculated. Results The operative time in the observation group was shorter than that in the control group（P<0.05）, and the intraoperative blood loss was less than that in the control group（P<0.05）, and there was no significant difference in hospital stay between the two groups（P>0.05）. There was no significant difference in the intervertebral height loss between the observation group and the control group （P>0.05）. The postoperative JOA score in the observation group was significantly higher than that in the control group （P<0.05）while the NDI was significantly lower than that in the control group（P<0.05）. There was no significant difference in bone grafting fusion rate between the observation group and the control group（P>0.05）, and the postoperative improvement rate in the observation group was higher than that in the control group （P<0.05）. Conclusion Anterior cervical corpectomy decompression and full?contact titanium mesh graft fusion can have good efficacy for cervical spondylotic myelopathy, and can significantly reduce the NDI.

摘要： ［摘要］ 目的 观察颈椎前路椎体次全切减压全接触钛网植骨融合治疗脊髓型颈椎病对患者颈椎功能障碍指数（NDI）评分的影响。方法 选择我院 2012 年 2 月至 2017 年 10 月收治的脊髓型颈椎病患者56 例，分对照组（28 例）和观察组（28 例），对照组进行颈椎前路髓核摘除加植骨内固定术，观察组进行颈椎前路椎体次全切减压全接触钛网植骨融合术。术后进行为期 6 个月的随访，比较两组患者手术时间、术中失血量、住院时间和椎间丢失高度，并统计患者术前和术后 6 个月 NDI、日本骨科学会（JOA）评分，计算植骨融合率和术后改善率。结果 观察组手术时间短于对照组（P<0.05），术中失血量少于对照组（P<0.05），住院时间与对照组无显著差异（P>0.05）；观察组椎间丢失高度与对照组无显著差异（P>0.05）；观察组术后 JOA 评分明显高于对照组（P<0.05），NDI 明显低于对照组（P<0.05）；观察组植骨融合率96.43%与对照组的82.14%无显著差异（P>0.05），术后改善率 86.94±3.52%高于对照组的 83.77±4.16%（P<0.05）。结论 颈椎前路椎体次全切减压全接触钛网植骨融合治疗脊髓型颈椎病疗效较好，可明显降低患者NDI。
