ROI-C与Zero—P在治疗单节段颈椎病中的比较

Comparison of ROI-C and Zero-P cervical fusion cage for single segmental cervical spondylosis

目的比较Zero—P与ROI—C治疗单节段颈椎病的早期疗效。方法回顾性分析2013年1月至2015年1月单节段颈椎病患者33例，按使用融合器类型分为ROI—C组（17例）和Zero—P组（16例）；均行术前、术后3个月、术后6个月颈椎X线片，比较两组手术时间、术中出血量、术前术后JOA评分、VAS评分、Cobb角、病变节段椎间高度及融合率。结果术后平均随访9．4个月；ROI—C组手术时间少于Zero—P组，差异有统计学意义（P〈0．05）；两组术中出血量比较差异未见统计学意义（P〉0．05）。两组术后JOA评分、Cobb角、病变椎间隙高度较术前均显著提高，术后VAS评分较术前显著降低，差异有统计学意义（P〈0．001）；但组间比较差异均未见统计学意义（P〉0．05）；所有患者均未出现吞咽困难等并发症。结论两种融合器治疗单节段颈椎病均可取得较好的临床疗效，但ROI．C具有操作简便，手术时间短等优点。

Objective To study the early effects of Zero-P and ROI-C segmental cervical spondylosis. Methods From January 2013 to January 2015, on patients with single 33 patients with cervical spondylosis were selected. All patients were classified as group ROI-C （17 cases） and group Zero-P （16 cases）, and Antero-posterior and lateral X-ray were performed before operation and 3 months, 6 months after operation. The operation time, intraoperafive blood loss, Japanese Orthopedic Association （JOA） scores, visual analog scale （VAS） scores and Cobb angle, the height of intervertebral space, fusion rate before and after operation were compared. Results All of the patients were followed up for 9. 4 months average. The operation time of group ROI-C was shorter than that of group Zero-P, the difference was significant （P 〈 0. 05）. There was no significant difference in the intraoperative blood loss between the two groups （P 〉 0. 05）. The mean JOA scores, Cobb angle, the height of intervertebral space increased significantly from pre-surgery to 3 months postoperatively, 6 months postoperatively in the two groups. The mean VAS scores decreased significantly from pre-operation to 3 months, 6 months postoper- atively in the two groups, the differences were significant（ P 〈 0. 001 ）. There was no significant difference in these data between the two groups at the same time （ P 〉 0. 05）. No postoperative dysphagia hap- pened in the two groups. Conclusions The ROI-C leads to similar clinical outcome compared to Zero-P for the treatment of the single segmental cervical spondylosis, while the ROI-C carries a simpler operation, shorter operation time.
