自稳型颈椎融合器在颈椎间盘突出症前路手术中的应用

Clinical application of stand-alone MC+PEEK cage in cervical disc herniation

目的探讨自稳型颈椎融合器治疗颈椎间盘突出症的临床效果。方法 2013-01-2014-01月,我科收治颈椎间盘突出症20例,单节段12例,双节段8例,采用椎间盘切除,自体髂骨植骨自稳型颈椎融合器椎间融合术治疗。结果本组20例均顺利完成手术,术后无相关并发症的发生,20例患者随访3~12个月,平均9个月,所有患者均达到骨性融合,平均融合时间4.20月,术后1周,3个月JOA评分较术前均明显升高,差别有统计学意义（P〈0.05）,随访期间所有患者均未出现融合器移位,椎间隙高度降低等情况。结论该融合器治疗颈椎间盘突出症,手术创伤小,是治疗颈椎间盘突出症的一种较好的方法。

Objective To study the clinical effects of operative treatment for cervical disc herniation with stand-alone MC＋PEEK cage. Methods 12 patients with cervical disc herniation in mono-segment and 8 patients in double-segment were operated. All the patients were reconstructed with the cage filled with autogenous cancellous illic-bone graft after discectomy. Results 20 patients were operated successfully and postoperative complications were not found. 20 patients were followed up for an average time of 9 months（from 3 to 12 months） and achieved bony fusion, the average time of bone graft fusion was 4.2 months. Japanese Orthopedic Association （JOA） of postoperative one week and three months were better than JOA of pre-operation, the differences were statistically significant（P〈0.05）. Displacement of cages and the loss of height of intervertebral space were not found. Conclusion Cervical disc herniation can be safely and micro-invasively operated with this new cage.
