摘要
目的 评价金属笼状椎间融合器 (BAK)、聚醚醚酮椎间融合器 (PEEK)、自体髂骨 3种颈前路融合材料的临床价值。方法 对 6 3例单节段脊髓型颈椎病患者行前路减压术 ,融合材料分别选用BAK、PEEK、自体髂骨 ,进行临床疗效及影像学评价。结果 临床症状改善率 3组差异无显著性 ;在骨性融合时间、椎间隙高度、颈椎弧度丧失、相邻节段后凸畸形等方面 ,PEEK组最优、BAK组次之、自体髂骨组较差 ,且自体髂骨组有供骨区并发症。结论 在 3种材料中 ,PEEK具有良好的生物力学优势和生物相容性 ,能维持椎间隙高度和恢复颈椎曲度 ,且价廉物美。
Objective To evaluate the clinical value of Bagby and Kuslich(BAK), polyether ether tetone(PEEK) and iliac bone autograft (IBAG) on cervical spine fusion. Methods 63 cases of single level cervical spondylotic myelopathy were undergone anterior decompression and fusion, and the fusion materials were BAK? PEEK or IBAG, respectively. The data of clinical value and radiography were analysed statistically. Results The improvement of symptom had no significant difference in the three groups. As for the time of bony fusion, the cervical intervertebral height, the arc loss of cervical spine,the adjacent kyphosis,the PEEK group was the best,the BAK group was the second, while the IBAG group was poor and had many complications in the donor. Conclusion The PEEK is the best in the 3 materials. It has excellent biomechanics properties and histocompatibility, which can maintain the cervical intervertebral height and the arc of cervical spine. Additionally,it is less expensive.
