摘要
[目的]评价聚醚醚酮椎间融合器在颈前路经椎间隙减压融合术中的临床应用及疗效。[方法]采用颈前路经椎间隙减压、聚醚醚酮椎间融合器植入固定融合术治疗颈椎病及颈椎间盘突出症45例，术后定期随访颈椎X线片，观察手术椎节的稳定性、融合情况、椎间隙高度恢复以及患者神经功能改善。[结果]随访6～12个月，手术节段稳定，椎间高度恢复满意，术后6个月绝大多数病例获得满意骨性融合。神经功能改善率45％～100％，平均84％。[结论]聚醚醚酮椎间融合器具有生物相容性好、弹性膜量小、x线透光等优点，有助于重建并维持椎间高度和生理曲度，促进植骨融合。
[Objective] To appraise the clinical effect of the cervical interbody fusion with PEEK cages after anterior decompression through disc space. [ Method ] Forty-five patients with cervical spondylosis or disc herniation were treated by using PEEK cages after anterior decompression. X-ray films were taken after operation to observe the stability, fusion rate and intervertebral disc height of the segments. The neural function was evaluated by JOA scoring system. [ Result ] All patients were followed up from 6 to 12 months. The operated segments were stable and height of disc space was reconstructed. Solid fusion was observed 6 months after operation. The improvement rate of neural function was 45 % - 100%, with an average of 84%. [ Conclusion ] The PEEK cage has the advantages of excellent biocompatibility, lower elastic modulus and radiolucence, which helps to reconstruct and maintain the intervertebral disc height and cervical lordosis effectively with satisfactory fusion rate.
