目的观察ProDisc-C人工椎间盘置换治疗双节段重症颈椎病的疗效.方法对17例双节段重症颈椎病患者进行人工椎间盘置换术,年龄36～59岁,术后随访时间24 ～55个月,手术前后观察视觉模拟评分(VAS)、JOA评分、颈椎整体曲度、置换节段活动度.结果术后第3、12、24个月VAS评分分别为(3.8±1.9)、(1.9±0.8)、(1.1±0.4)分,与术前(6.3±2.7)分比较差异有统计学意义(P＜0.05)；术后第3、12、24个月JOA评分分别为(13.4±1.5)、(15.2±1.1)、(15.9±1.4)分,与术前(8.7±2.1)分比较差异有统计学意义(P＜0.05)；术后24个月颈椎整体曲度与术前比较差异无统计学意义(P＞0.05).术后24个月置换节段活动度较术前差异有统计学意义(P＜0.05).结论人工颈椎间盘置换术治疗双节段重症颈椎病疗效良好,术后能保持良好的颈椎活动度.

Objective To investigate the clinical effect of ProDisc-C cervical disc replacement for two-segment severe cervical spondylosis.Methods Seventeen cases of two-segment severe cervical spondylosis aged from 36-59 years old were treated with artificial cervical disc replacement.The patients were followed up for 24 to 55 months after operation.The visual analogue scale (VAS),Japanese Orthopedic Association (JOA) scores,cervical curvature overall and the range of motion of the replacement segment were evaluated pre-and 3,12 and 24 months post-operation.Results The VAS scores at 3,12 and 24 months post-operation were 3.8 ± 1.9,1.9 ± 0.8 and 1.1 ± 0.4 respectively,which were significantly reduced as compared with pre-operation (6.3 ± 2.7,P ＜ 0.05).The JOA scores at 3,12 and 24 months postoperation were 13.4 ± 1.5,15.2 ± 1.1 and 15.9 ± 1.4 respectively,which were significantly increased as compared with pre-operation (8.7 ± 2.1,P ＜ 0.05).There was no statistically significant difference in the cervical curvature overall before and 24 months after operation (P ＞ 0.05).There was significant difference in the range of motion of the replacement segmentl before and 24 months after operation (P ＜ 0.05).Conclusion The clinical effect of ProDisc-C cervical disc replacement for two-segment severe cervical spondylosis is satisfactory and it can maintain good cervical activity after operation.
