Mobi-C颈椎人工间盘置换治疗单节段颈椎间盘突出症的效果

Effect of Mobi-C cervical artificial disc replacement in the treatment of single proplase of cervical intervertebral disc

目的：探讨Mobi-C颈椎人工间盘置换治疗单节段颈椎间盘突出症的近期效果。方法：对应用Mobi-C颈椎人工间盘置换治疗的12例单节段颈椎间盘突出症患者于术前、术后（1～2 d ）及末次随访时进行全面的影像学和临床评价，并进行问卷调查。结果：本组病例随访6～24月，平均13个月。 Odom临床疗效评价优10例，良2例。患者的颈部及上肢疼痛明显缓解，VAS评分术后下降了5．8分（P＜0．05），末次随访时下降了5．5分（P＜0．05）。颈椎功能障碍指数（NDI）和SF-36生活质量量表评分明显改善，患者的生活质量明显提高。除3例患者发生异位骨化外，未发现相邻节段退变加速。结论：保留颈椎活动度的Mobi-C颈椎人工间盘置换对颈椎间盘突出症的患者近期疗效确切，可明显提高患者的生活质量。

Objective：To research the short-term effect of Mobi-C cervical artificial disc replacement （CADR） therapy in patients with single proplase of cervical intervertebral disc .Methods：Mobi-C artificial cervical disc was applied to treat 12 cases of single proplase of cervical intervertebral disc .The data about clinical observation , imaging evaluation and questionnaire were collected at preoperative , postoperative （ 1-2 days ） and the end follow-up.Results：The patients were followed up for 6 to 24 months,average 13 months.All the patients were satisfactory to the outcome , excellent in 10 cases and good in 2 cases according to Odom criterion .The pain in upper limb and neck were significantly relieved, the VAS score immediately decreased 5.8 points after operation（P〈0.05）, and 5.5 points at the last follow-up（P〈0.05）.NDI and SF-36 improved obviously,which meant the patient′s quality of life improved obviously .Degeneration at the adjacent segments was not found in addition to 3 patient with heterotopic ossification .Conclusions：Mobi-C CADR therapy reserving mobility of cervical spine has a good effect in the early stage , and can improve the quality of life of the patients .
