摘要:

背景:颈椎前路椎间盘切除减压、人工椎间盘置换目前已广泛应用于颈椎退行性疾患的治疗,其近期疗效虽令人鼓舞,但仍缺乏长期、综合评价。
目的:观察一组颈椎前路椎间盘切除减压、Mobi-C人工椎间盘置换病例5年以上随访结果。 
方法:2009年1至9月解放军第309医院收治符合颈椎间盘置换指征的颈椎病变手术患者25例,至今获随访19例。所有患者均行经前路椎间盘切除减压、Mobi-C人工颈椎间盘假体置换,共植入 Mobi-C人工颈椎间盘假体23枚。所有患者在颈椎伸屈侧位 X射线片上测量置换节段活动度;在侧位X射线片上采用McAfee异位骨化分级方法评定异位骨化情况;根据颈椎MRI片,参考Pearce分级判断邻近节段退变情况;采用NDI评分评估患者颈椎功能;目测类比评分评价患者疼痛改善情况。 
结果与结论:19例患者获得59-65个月随访,平均随访62个月。术前及末次随访时置换节段活动度比较差异无显著性意义(P > 0.05)。随访期内发生异位骨化2例,发生邻近节段退变1例,未见假体松动、移位等并发症。末次随访时目测类比评分及NDI 评分均较术前明显降低,差异有显著性意义(P < 0.05)。提示在合理选择适应证的前提下,采用 Mobi-C人工颈椎间盘假体行人工椎间盘置换治疗退行性颈椎疾患,5年随访临床疗效满意:置换节段活动度维持较好,异位骨化及邻近节段退变的发生率较低。

Abstract:

BACKGROUND: Anterior cervical discectomy and intervertebral disc replacement have been extensively used in treatment of cervical degenerative disease. Its short-term therapeutic effects are encouraging, but it lacks of long-term and comprehensive evaluation.
OBJECTIVE: To observe the follow-up results of a group of cases of anterior cervical discectomy and Mobi-C intervertebral disc replacement for more than 5 years.
METHODS: A total of 25 cases of cervical spondylosis were treated in the 309 Hospital of Chinese PLA from January to September 2009. 19 of them were followed up. All patients received anterior cervical discectomy and Mobi-C intervertebral disc replacement. Twenty-three Mobi-C intervertebral disc prostheses were implanted. The range of motion was measured using lateral X-ray films during extension and flexion. Ectopic ossification was assessed by McAfee method. According to the cervical vertebra MRI images, the degeneration of adjacent segments was determined using Pearce classification. NDI score was used to evaluate the function of cervical spine. Pain improvement was evaluated using visual analogue scale score.
RESULTS AND CONCLUSION: A total of 19 patients were followed up for 59-65 months, averagely 62 months. No significant difference in range of motion was detected before surgery and during final follow-up (P > 0.05). Ectopic ossification in two cases and the degeneration of adjacent segments in one case were found during final follow-up. No prosthesis loosening or displacement appeared. Visual analogue scale score and NDI score were significantly lower during final follow-up compared with that before surgery (P < 0.05). These results indicate that under the premise of reasonable choice of indications, the therapeutic effect of Mobi-C intervertebral disc  replacement for degenerative cervical spondylosis was satisfactory in five-year follow-up. The range of motion was good, and the incidences of ectopic ossification and the degeneration of adjacent segments were low.
