双嵌式颈椎融合器治疗脊髓型颈椎病早中期效果

The early-to-mid treatment efficacy of applying ROI interbody fusion cage in cervical spondylotic myelopathy

目的:评估双嵌式颈椎融合器(ROI-C)治疗脊髓型颈椎病的临床疗效及影像学效果。方法:2012年5月-2013年6月我科应用颈椎压力固定器对21名患者行颈椎前路减压椎间盘切除椎体融合术。应用JOA功能评分评价临床疗效,并于术前,术后3 d、术后3个月、术后6个月行常规X线正侧位片检查,评估椎体间融合情况及椎间高度,并记录每例病例手术时间、出血量及手术相关并发症情况。结果:JOA评分随时间顺序逐渐升高,6个月内所有病例椎间全部融合,椎间高度在术后3 d即显著恢复,3个月内下降,术后6个月趋于稳定。在随访期间,未发生手术相关并发症。结论:应用双嵌式颈椎融合器治疗脊髓型颈椎病可在早中期达到较好的临床疗效。

Objective:To observe the clinical effect and radiological outcomes of ROI interbody fusion cage in cervical spondylotic myelopathy. Methods:21 patients were treated with lumbar disc excision and cervical vertebra fusion with ROI cage trans anterior approach. Clinical effect was evaluated by Japanese Orthopaedic Association(JOA) score for cervical function.Each patient underwent cervical anteroposterior and lateral radiographs,CT scanning before operation,at 3 days,3months,and 6 months after operation to assess fusion effect. Intervertebral height was measured. The time of operation,intraoperative blood loss and complication relative to opration were recorded. Results:As time goes on,the score of JOA was increased gradually after operation,and patients were all cured after 6 months. The fusion rate was 100%. No complication was found. Conclusion:Favorable early and midterm outcomes may be yielded in patients with cervical spondylotic myelopathy treated by anterior cervical discectomy and fusion with ROI interbody fusion cage.
