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.
