摘要:

背景:目前治疗颈椎病的最常用方法是颈椎前路椎管减压植骨内固定。为了减少钛板厚度对食管及咽部的影响,以及简化操作步骤,低切迹钛板或零切迹的内固定材料不断涌现。自锁式融合器MC+®和ROI-CTM的出现,为颈椎病前路手术提供了一个解决钛板切迹、更加简便的操作办法。
目的:应用MC+®或ROI-CTM融合器结合颈椎前路椎管减压植骨内固定治疗颈椎病,观察两种融合器对术后早期颈椎稳定性、融合率以及临床疗效的影响。
方法:2013年6月至9月对36例颈椎病患者实施单椎间隙颈椎前路椎管减压内固定治疗,根据使用的融合器类型分为MC+®组和ROI-CTM组。所有患者均进行术前、术后3 d、术后3个月的颈椎正侧位、过屈过伸位X射线片及颈椎CT检查,测量颈椎曲度、椎间隙高度、病变椎体角度位移及水平位移;并行颈部疼痛目测类比评分、Bazaz吞咽困难分级评估。
结果与结论:术后两组颈椎曲度和椎间隙高度均较术前显著增加(P < 0.05)。无论术后3 d抑或术后3个月,颈椎曲度和椎间隙高度在两组间差异无显著性意义(P > 0.05)。MC+®组术后3 d角度位移和水平位移较术前显著增加(P < 0.05),术后3个月与术前、术后3 d相比均显著减小(P均< 0.05)。ROI-CTM组从术前到术后3 d、术后3个月,角度位移和水平位移呈明显的下降趋势。无论术后3 d抑或术后3个月,MC+®组的角度位移和水平位移均大于ROI-CTM组。术后3个月两组融合率差异无显著性意义(P > 0.05)。Bazaz吞咽困难分级和颈部疼痛目测类比评分在两组间差异无显著性意义(P > 0.05)。提示颈前路椎管减压植骨内固定结合MC+®/ROI-CTM颈椎融合器治疗单节段颈椎病,均具有临床疗效可靠,操作简单、咽部疼痛不适少的特点。MC+®具有价格较为低廉的优点,结合颈椎外固定治疗可达到病变椎节稳定性的要求。ROI-CTM融合器能够达到更满意的术后即刻稳定性,是治疗颈椎病更为满意的选择。总之,两种自锁式融合器各有优缺点,应根据患者经济情况、椎节稳定性要求选择更为合适的融合器。

Abstract:

BACKGROUND: Anterior cervical decompression and internal fixation is the most common treatment for cervical spondylosis at present. Low profile or zero notch internal fixation materials are constantly emerging in order to reduce the effect of titanium plate thickness on the esophagus and pharynx, and to simplify the operation procedure. The self-locking interbody fusion MC+® and ROI-CTM provides a solution of titanium plate notch effect and more simple operation methods for anterior cervical operation.
OBJECTIVE: To compare the effect on cervical stability, fusion rate and clinical efficacy by anterior cervical decompression and internal fixation using various self-locking interbody fusion MC+® or ROI-CTM to treat cervical spondylosis.
METHODS: From June to September 2013, we treated 36 cervical spondylosis patients by anterior cervical 
decompression and internal fixation. According to different types of intervertebral fusion device, the patients were divided into two groups: MC+® group and ROI-CTM group. Each patient underwent cervical anteroposterior and lateral radiographs, lateral flexion extension radiographs, CT scanning before operation, at 3 days, and 3 months after operation. Cervical curvature, intervertebral height, vertebral angle displacement and horizontal displacement were measured. Cervical pain visual analog scale score and Bazaz dysphagia score were evaluated.
RESULTS AND CONCLUSION: In both groups, cervical curvature and intervertebral space height showed significantly increases after operation (P < 0.05), but no significant difference in cervical curvature and intervertebral space height was detected between two groups at 3 days or 3 months after operation (P > 0.05). In MC+® group, angle displacement and horizontal displacement showed significant increases in 3 days after operation (P < 0.05), but angle displacement and horizontal displacement at 3 months after operation showed significantly decrease compared with those of before operation and 3 months after operation (P < 0.05). In ROI-CTM group, angle displacement and horizontal displacement showed a marked decline at 3 days and 3 months after operation. Angle displacement and horizontal displacement were significantly higher in MC+® group than in the ROI-CTM group at 3 days or 3 months. No significant differences in fusion rate were detected between both groups at 3 months (P > 0.05). No significant differences in cervical pain visual analog scale score and Bazaz dysphagia score were detectable between both groups (P > 0.05). These data indicated that anterior cervical decompression and internal fixation combined with MC+® or ROI-CTM cervical fusion cage for single-segment cervical spondylosis has reliable clinical therapeutic effects, and the operation is simple; uncomfortable throat pain is less. MC+® cage was relatively cheap. The combination with cervical external fixation can achieve the requirement of vertebral stability. ROI-CTM cage can achieve satisfactory postoperative immediate stability, and is a satisfactory choice for treating cervical spondylosis. In conclusion, the two kinds of locking fusion cage have their advantages and disadvantages. A suitable fusion cage should be selected according to patients’ economic situation and vertebral stability requirements.
