矩形钛质颈椎椎间融合器在颈椎前路融合术中的应用以及近期效果观察

目的 探讨矩形钛质颈椎椎间融合器(SynCage-C)在颈椎前路椎问盘切除、椎体间植骨融合术中的应用价值。方法应用SynCage-C行颈椎病前路椎间盘切除后椎体间融合19例,平均随访9个月(6～14个月)。结果本组均为颈椎病患者,脊髓型16例、神经根型3例。平均年龄48岁(34～66岁),男性13例,女性6例。单节段融合16例,双节段3例。每节段平均手术时问40min,平均出血60ml。术后平均围领保护8．5周。3个月时颈椎侧位X线片显示融合良好。19例患者中仅有1例因戴围领超过3个月而感颈部僵直,1例有短暂髂骨取骨区疼痛。本组未见融合节段曲度不良、反曲、Cage下沉、融合不良。结论SynCage-C操作简单,可以有效恢复和维持椎间隙高度,植入后即刻稳定,椎间融合良好,取骨区创伤小。

The application and early result of rectangle titanium cage in the anterior cervical spine fusion

Objective To evaluate the value of rectangle titanium cage (SynCage C) in the anterior cervical spine fusion Methods Nineteen patients underwent anterior cervical discectomy and interbody fusion using SynCage C with average follow up of 9 months Results All cases had cervical spondylosis with 13 cases of myelopathy and 6 cases of radiculopathy One level fusion were 16 cases and two levels were 3 cases The mean operation time was 40 minutes per level with average bleeding 60 ml Patients were asked to wear a hard collar for average 8.5 weeks after the operation The fusion was solid on lateral view X ray films three months post operation Only 1 case had neck stiffness due to prolonged collar protection and another case had short term pain on bone dorner site There were no other complications such as cage subsidence, displacement, milaligment and kyphosis of cervical spine Conclusion The SynCage C can resort and maintain the intervertebral space effectively with the advantage of immediate stability, satisfactory fusion and easy to use.
