颈椎椎体间融合器的临床应用(附135例报告)

Anterior Decompression and Fusion with Cages in the Cervical Spine

目的 :观察比较 3种颈椎椎体间融合器前路减压后椎体间融合的固定及融合效果。方法 :采用BAK、CHTF和InterFix 3种颈椎椎体间融合器行颈椎病及颈椎间盘突出症前路减压后椎体间融合 135例 ,其中BAK 6 5例 ,CHTF 42例 ,InterFix技术 2 8例。术后颈椎X线片及CT检查 ,观察手术椎节的稳定性和融合情况。结果 :随访 8～ 31月 ,施术节段稳定 ,3种颈椎椎体间融合器固定融合率无显著差异。结论 :颈椎椎体间固定融合技术使施术椎节立即稳定 ,避免了自体植骨引起的并发症 ,可作为替代传统颈前路椎体间植骨融合术的方法之一。

Objective:To observe and compare the stability and fusion rate of three kinds of the interbody fusion cages after anterior decompression in the cervical spine.Methods:135 patients with cervical spondylosis and disc herniation were stabilized by using interbody fusion cages after anterior decompression,among them,65 cases with BAK,42 cases with CHTF and 28 cases with InterFix technique.X ray films and CT were taken after operation to observe the stability and fusion of the segments.Results:The patients were followed up from 8 months to 31 months.The operated segments were stable.There was no difference in the fusion rate among three interbody fusion techniques.Conclusion:The immediate stability of the operated segments can be obtained by using interbody fusion cages.These techniques eliminate the complications of autograft and may be an alternative for replacing the traditional cervical interbody fusion with bone graft.
