采用自稳式双嵌片融合系统前路手术治疗神经根型颈椎病

目的观察颈前路手术应用自稳式双嵌片融合系统(ROI-C)治疗神经根型颈椎病的临床效果。方法对35例神经根型颈椎病患者采用前路椎间盘切除、神经根减压、ROI-C植骨固定治疗。观察术前及术后3、6、12个月颈椎功能评分变化和椎间隙高度改变及植骨融合情况。结果 35例均获得随访,时间12~32个月。颈椎障碍指数由术前的36.1%±12.8%减少至术后12个月的9.8%±4.5%,差异有统计学意义(P0.05)。术后优良率为91.4%。椎间隙高度术前为5.1 mm±1.6 mm,术后12个月时为7.8 mm±0.5 mm,差异有统计学意义(P0.05)。2例患者分别出现声音嘶哑和吞咽困难,术后2周自愈。术后6个月X线或CT检查39个融合节段均获骨性融合。结论 ROI-C有良好的组织相容性,符合人体生物学特性,应用其治疗神经根型颈椎病具有创伤小、并发症少、融合率高、疗效好的优点。

The research on the application of double-plate self-locking cage for treatment of the cervical spondylotic radiculopathy

Objective To discuss the efficacy of a new double-plate self-locking interbody fusion device( ROI-C) in the anterior cervical discectomy and fusion( ACDF) for treatment of cervical spondylotic radiculopathy. Methods The anterior cervical discectomy,radicular decompression and interbody fusion by RIO-C were performed in 35 pa-tients. The neck disability index( NDI) was recorded preoperatively and in the follow-up time to evaluate the clinical outcome, meanwhile, the preoperative and postoperative X-ray films of 3,6,12months were accumulated to measure the height of interbody space and the rate of fusion. Results Thirty-five cases were followed up for 12~32 months. NDI decreased from 36. 1% ± 12. 8% preoperatively to 9. 8% ± 4. 5% in 12 months postoperation ( P<0. 05 ) , the excellent-good rate was 91. 4%. The height of the disc space increased from 5. 1 mm ± 1. 6 mm preoperatively to 7. 8 mm ± 0. 5 mm in 12 months postoperation, the change was statistically significant(P<0. 05). Dysphagia in one pa-tient and hoarseness in another patient were found, both of them were recovered spontaneously in two weeks. All of the 35 cases(39 levels)achieved bony fusion in 6 months according to X-ray film or CT image judgment. Conclusions There are many advantages in the treatment for cervical spondylotic radiculopathy with the ROI-C, such as good bi-ological histocompatibility, minimally invasive procedure, less complications, high fusion rate, optimistic treatment outcome.
