Abstract:
[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.
