摘　　要：目的：探讨自稳型颈椎融合器在颈椎前路融合手术中应用的临床效果。方法：2011年1月至2014年1月,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颈椎疾患50例,其中男32例,女18例;年龄30～79岁,平均53.30岁;颈椎病22例,外伤性颈椎间盘突出症26例,颈椎失稳2例;单节段32例,双节段15例,3节段3例。采用日本骨科协会评定标准（Japan Orthopedic Association,JOA）对神经功能进行评估;采用Otani 分级方法对疗效进行评定;定期拍摄颈椎正侧位X线片和动力位X线片观察颈椎曲度和骨融合情况以及有无内固定相关并发症;采用Suk法评估骨融合情况。结果：50例患者均获得随访,时间6～36个月,平均20个月。术后未见明显的手术相关并发症,均达到骨性融合,平均融合时间 4.30个月。JOA评分术后1周为16.10±2.20,术后6个月为16.40±2.35,较术前的10.60±3.00均明显提高（P〈0.05）.采用Otani分级方法进行疗效评定,优40例,良 9例,可1例。随访期间未出现明显的吞咽困难、融合器移位等内固定相关并发症。结论：在颈椎前路融合手术中使用自稳型颈椎融合器疗效满意,且手术创伤小,能减少手术相关并发症的发生,是颈椎前路融合手术中一种较好的融合方法。Objective：To explore the effect of clinical application of stand-alone MC＋PEEK cage in anterior cervical fusion. Methods：From January 2011 to January 2014, 50 patients were treated with the MC＋PEEK cage filled with autogenous cancellous illic-bone graft after anterior cervical discectomy. There were 22 patients with cervical spondylosis, 26 patients with traumatic cervical disc herniation, 2 patients with cervical instability in these patients. There were 32 males and 18 females, aged from 30 to 79 years old with an average of 53.30 years old. There were 32 patients with single segment, 15 patients with double segments and 3 patients with three segments. Cervical AP and lateral and the flexion-extension X-rays were regularly taken in order to assess the cervical physiological curvature, the graft fusion and internal fixation related complications. Nerve function, clinical effect and bone fusion were respectively evaluated according to Japan Orthopedic Association （JOA）, Otani grade and Suk method. Results：All patients were followed up from 6 to 36 months with an average of 20 months. No correlated surgical complications were found and all patients obtained bony fusion with an average time of 4.30 months. JOA score had significantly improvement after surgery（P〈0.05）. The JOA score was 10.60±3.00 before surgery and 16.10±2.20, 16.40±2.35 at one week and six months after surgery respectively. According to Otani grade, 40 cases got excellent results, 9 good, 1 fair. No significant dysphagia and internal fixation related complications such as displacement of cages were found during the follow-up period. Conclusion：Using this cage in anterior cervical fusion can obtain satisfactory clinical effect with less operation injury and reduce the complications. It is a better fusion method in anterior cervical fusion.
