摘要
背景:颈前路手术对颈椎矢状位平衡参数的影响逐渐被关注,目前对于双节段颈椎病的术式选择缺乏明确可行的临床指南,寻求最适合的固定方式更有益于此类型患者。目的:对比颈前路减压不同融合装置对邻近双节段脊髓型颈椎病术后颈椎矢状位参数变化的影响。方法:回顾性分析2018年3月至2020年9月聊城市人民医院收治的符合选择标准的邻近双节段脊髓型颈椎病患者44例,全部患者均行前路椎间盘切除椎管减压融合治疗,根据椎间融合装置的不同分为2组,零切迹组(zero-p组)纳入患者23例,钛板联合cage组(cage组)纳入患者21例。所有患者术前完善颈椎正侧位X射线片、颈椎CT及MRI检查,末次随访时拍摄颈椎正侧位X射线片,手术前后于X射线片上测量颈椎矢状位平衡参数,包括颈椎前凸角(C2-7 Cobb角)、颈椎矢状位垂直距离、病椎局部前凸角和T1倾斜角。记录手术时间、术中出血量、末次随访椎间融合以及术后吞咽障碍发生情况,并于术前及术后评估患者日本骨科学会颈椎评分。计算两组患者手术前后颈椎矢状位参数变化值并对比其差异。结果与结论:①两组患者均顺利完成手术并获得随访,zero-p组手术时间较cage组短,术中出血量较cage组少,但差异无显著性意义(P>0.05);②cage组术后吞咽障碍发生率(7/21,33%)高于zero-p组(3/23,13%),差异有显著性意义(P<0.05);③末次随访时,两组临床疗效相同,均骨性融合;组内比较发现两组颈椎矢状位参数指标均较术前改善(P<0.05);组间比较末次随访时各矢状位参数差异均无显著性意义(P>0.05);两组间颈椎矢状位垂直距离、C2-7 Cobb角、T1倾斜角变化值比较差异均无显著性意义(P>0.05),但zero-p组病椎局部前凸角变化值较cage组小,差异有显著性意义(P<0.05);④提示前路椎间盘切除椎管减压融合过程中使用zero-p与钛板联合cage均能有效改善颈椎矢状面平衡,钛板联合cage椎间融合可以更好地重建患者颈椎前凸曲度,对于融合装置的选择还应综合考虑手术并发症的发生情况。
BACKGROUND:The impact of anterior cervical surgery on the sagittal balance parameters of the cervical spine is gradually being paid attention to.Currently,there is a lack of clear and feasible clinical guidelines for the selection of surgical methods for two-level cervical spondylosis,aiming to find the most suitable fixation method that is more beneficial for this type of patient.OBJECTIVE:To compare the effects of different fusion devices for anterior cervical decompression on the changes of cervical sagittal parameters after surgery for adjacent two-level cervical spondylotic myelopathy.METHODS:A total of 44 patients with adjacent two-level cervical spondylotic myelopathy underwent anterior cervical discectomy and fusion from March 2018 to September 2020 in Liaocheng People’s Hospital were retrospectively analyzed in the study,and they were divided into zero-p group(23 cases)and cage group(21 cases).All patients underwent anteroposterior X-ray,three-dimensional CT reconstruction and MRI examination before operation.At the last follow-up,the anteroposterior X-ray films of cervical spine were taken.The sagittal balance parameters of the cervical spine were measured before and after surgery,including cervical lordotic angle(C2-7 Cobb),C2-C7 sagittal vertical axis,segmented lordotic angle and T1 slope.The surgical time,intraoperative bleeding,last follow-up intervertebral fusion,and postoperative swallowing disorders were recorded,and Japanese Orthopaedic Association score on the patient was evaluated before and after surgery.The changes in cervical sagittal parameters before and after surgery were calculated and their differences were compared between the two groups.RESULTS AND CONCLUSION:(1)Both groups of patients successfully completed the surgery and received follow-up.The zero-p group had shorter surgical time and less intraoperative bleeding compared to the cage group,but the difference was not statistically significant(P>0.05).(2)The incidence rate of postoperative swallowing disorders in the cage group(7/21,33%)was higher than that in the zero-p group(3/23,13%),and the difference was statistically significant(P<0.05).(3)At the last follow-up,the clinical efficacy of the two groups was the same;all patients had bone fusion.Comparison within the group showed that the sagittal parameters of the cervical spine in both groups improved compared to before surgery(P<0.05).There was no statistically significant difference in sagittal parameters between groups(P>0.05),and there was no statistically significant difference in changes in C2-C7 sagittal vertical axis,C2-7 Cobb angle,and T1 slope between the two groups(P>0.05).However,the segmented lordotic angle changes in the zero-p group were smaller than those in the cage group,and the difference was statistically significant(P<0.05).(4)It is indicated that the use of zero-p and titanium plate combined with cage during anterior cervical discectomy and fusion surgery can effectively improve cervical sagittal balance.Titanium plate combined with cage intervertebral fusion can better reconstruct the patient’s cervical lordosis and curvature.The selection of fusion devices should also comprehensively consider the occurrence of surgical complications.
