颈前路减压Mc^+颈椎间融合器的临床应用

Clinical application of anterior cervical decompression and implantation of Mc^+ cervical cage

目的探讨Mc+颈椎间融合器在颈前路融合术中的可行性及临床疗效。方法17例颈椎疾患患者行颈前路椎间盘切除减压、Mc+颈椎间融合器椎间融合术,术前及术后3d、3个月、6个月、1年进行JOA评分,观察神经功能恢复情况,并摄X线片观察椎间高度及植骨融合率。结果未见手术相关的并发症发生,患者术后次日下床活动,16例患者于术后第1天症状明显改善,术后椎间高度较术前明显增高。所有病例均获得平均10个月的随访,JOA评分平均恢复率80%,6个月均获骨性融合,融合椎体无畸形,融合器无移动。结论Mc+颈椎间融合器能使融合节段获得即刻稳定,能有效恢复和维持椎间高度和颈椎生理弧度,融合率高,近期疗效满意。

Objective To investigate the cage used in the anterior cervical fusion. Methods feasibility and clinical effectiveness of Mc＋ cervical Seventeen patients with cervical disease underwent anterior cervical discectomy, decompression and implantation of Mc＋ cervical cage. The JOA score was evaluated preoperatively and 3 days, 3 monthes, 6 monthes and 1 year after surgery. The neurofunctional condition was observed and plain radiography was taken to survey the interspinal height and fusion rate of bone graft. Results There was no any complication related to operation. The patients were mobilized on the next day after operation. Sixteen patients had obvious clinical improvement. The interspinal height observed on the plain radiography rechecked postoperatively heightened obviously compared with that before operation. All patients were followed up for an average of 10 monthes. The average recovery rate of JOA score was 80%. All patients gained osseous fusion 6 monthes after operation. The fusional centrum did not have any malformation and the cage did not move. Conclusion The Mc＋ cervical cage is able to make the fusion segment have immediate stability,as well as to retrieve and maintain the interspinal height and cervical physiological radian effectively. Besides, the fusion rate is high and the short-term curative effect is satisfactory.
