摘要:

文题释义:

零切迹融合器ROI-C:又称为前路颈椎桥形固定嵌片融合器,通过前入路进行颈椎关节融合的外科植入体。前路颈椎间盘融合器ROI-C是在切除颈椎椎间盘后,通过填充自体骨、同种异体骨源骨替代物植入椎间盘形成人造椎间盘,将桥形固定嵌片固定在上下椎体之间,在前路椎体上可做到完全无突出的零切迹。

双节段脊髓型颈椎病:指因各种原因使得3个椎体2个间隙的颈椎椎骨间连接结构退变,如椎间盘突出、椎体后缘骨刺、钩椎关节增生、后纵韧带骨化、黄韧带肥厚或钙化,导致颈椎脊髓受压或脊髓缺血,继而出现脊髓的功能障碍等症状的一种颈椎病。

背景:自锁式自稳型零切迹颈椎融合器ROI-C是传统钛板融合器的改进和升级,但目前ROI-C内固定系统用于双节段脊髓型颈椎病的全面评估临床研究不多,其治疗脊髓型颈椎病的临床试验缺乏全面的临床疗效评估。

目的:全面系统评估小切口颈前路自锁式自稳型零切迹颈椎融合器ROI-C治疗双节段脊髓型颈椎病的临床疗效。

方法:选择2016年9月至2018年3月广东药科大学附属第一医院双节段脊髓型颈椎病患者57例,其中男30例,女27例,年龄34-77岁,其中33例进行小切口颈椎前路自锁式自稳型零切迹颈椎融合器ROI-C植入治疗(观察组),另24例进行小切口颈椎前路钛板内固定治疗(对照组)。术后2周及1,3,6,12个月评估JOA评分、颈椎功能障碍指数、Odom标准手术疗效、目测类比评分、吞咽困难程度、颈椎前凸Cobb角、融合节段成角、椎间盘高度及颈椎融合率。研究得到广东药科大学附属第一医院伦理委员会批准。

结果与结论:①两组术后Odoms手术标准评估比较差异无显著性意义(P > 0.05);57例患者均获得术后12个月随访,均未见内固定松脱及椎体结构的改变,未见嵌片或钛板松脱、断裂等并发症发生;②两组术后的JOA评分、NDI评分、目测类比评分均较术前明显改善(P < 0.05),但两组组间比较差异无显著性意义(P > 0.05);③观察组术后2周、1个月的吞咽困难发生率明显低于对照组(P < 0.05),两组术后3,6,12个月比较差异无显著性意义(P > 0.05);④两组术后的颈椎前凸Cobb角、融合节段成角、椎间盘高度均较术前明显改善(P < 0.05),但两组组间比较差异无显著性意义(P > 0.05);⑤两组末次随访颈椎融合率均>95%,融合效果良好,两组术后不同时间点的融合率比较差异均无显著性意义(P > 0.05);⑥结果表明,小切口颈前路自锁式自稳型零切迹颈椎融合器ROI-C和前路钛板内固定治疗双节段的脊髓型颈椎病均有显著疗效,但使用ROI-C能够减少术后吞咽困难发生率。

Abstract:

BACKGROUND: Self-locking self-stabilizing zero-profile cage ROI-C is advanced from the traditional titanium plate fusion cage, but the systematic studies on ROI-C internal fixation system applied in the comprehensive evaluation of two-level cervical spondylotic myelopathy are few.

OBJECTIVE: To comprehensively evaluate the clinical efficacy of small-incision anterior cervical self-locking self-stabilizing zero-profile cage ROI-C in the treatment of two-level cervical spondylotic myelopathy.

METHODS: Fifty-seven patients with two-level cervical spondylotic myelopathy at the First Affiliated Hospital of Guangdong Pharmaceutical University from September 2016 to March 2018 were selected, including 30 males and 27 females, aged 34-77 years old. Of which, 33 patients underwent small-incision anterior cervical self-locking self-stabilizing zero-profile fusion cage ROI-C implantation (observation group), and another 24 patients received small-incision cervical anterior titanium internal fixation (control group). The JOA score, Neck Disability Index, Odom criteria, Visual Analogue Scale score, dysphagia degree, Cobb angle of cervical lordosis, angle of fusion segment, and disc height and cervical fusion rate were assessed at 2 weeks and 1, 3, 6, and 12 months after surgery. The study was approved by the Ethics Committee of the First Affiliated Hospital of Guangdong Pharmaceutical University.

RESULTS AND CONCLUSION: (1) There was no significant difference in the Odoms criteria between two groups (P > 0.05). All 57 patients were followed up for 12 months after surgery. No internal fixation loosening or vertebral structure changes were found. No complications such as loosen and broken of titanium plate occurred. (2) Postoperative JOA score, Neck Disability Index, and Visual Analogue Scale in the two groups were significantly improved compared with those before surgery (P < 0.05), but there was no significant difference between two groups (P > 0.05). (3) The incidence of dysphagia at 2 weeks and 1 month in the observation group was significantly lower than that in the control group (P < 0.05). There was no significant difference between two groups at 3, 6, and 12 months after surgery (P > 0.05). (4) The Cobb angle of cervical lordosis, angle of fusion segment, and disc height were significantly improved in both groups after surgery (P < 0.05), but there was no significant difference between two groups (P > 0.05). (5) The cervical fusion rate at the last follow-up in both groups was > 95%, and the fusion effect was good. There was no significant difference in the fusion rate at different time points between two groups (P > 0.05). (6) These results indicate that the small-incision anterior cervical self-locking self-stabilizing Zero-profile interbody fusion ROI-C and anterior titanium plate internal fixation exert significant effects in the treatment of two-level cervical spondylotic myelopathy. However, ROI-C can reduce the incidence of postoperative dysphagia.
