Methods　A total of 45 patients underwent cervical spine fusion surgery from Feb 2004 to Aug 2007 were reviewed retrospectively. Patients in group A (22 patients) were underwent discetomy and cage fusion, and ingroup B (23 patients) were treated with discetomy and autogenous tri-cortical iliac crestgraft fusion. Postoperative JOA scorewere evaluated. Cervical lordosis, height of intervertebral space and fusion ratewere also assessed on radiographs 3 month, 6months, and 12 months after operation. Fusion evidencewas observed by CT scan. Results　Allpatientswere followed up foran averaged period of12 month (range, 6 to 18 months). At 1 year follow-up, the cervical lordosis of group A (9. 47±2. 31) was better than group B (6. 90±3. 63) with statistical significance (P0. 05). The heightof intervertebral space inboth groups and recovery of spinal cord functionwere satisfactorywith no statistical difference.Conclusion　The PEEK cage is a good selection for anterior cervical spine fusion. 【keywords】PEEK cervical spondylosis;interbody fusion 颈椎前路手术行椎体间融合手术的关键是恢复和长久维持颈椎的生理弧度和椎间隙的高度。传统的自体三面皮质髂骨植骨方法虽然在融合率方面效果良好，但实践证明在稳定性和颈椎生理弧度及椎间隙高度的长期维持上不能令人满意，椎间融合器的使用在很大程度上弥补了上述缺点[1] [2]。2004年月，我们对例颈椎疾病患者采用新型材料聚醚醚酮（Poly?Ether?Ether?Ketone?，PEEK）生产的Cage行椎体间融合，现报告如下1.资料方法1.资料?）术前均行普通X线正侧位片、CT及MRI检查，以明确病变部位、性质及脊髓损害程度、手术节段。.2
