Objective:To discuss the efficacy of dynamic cervical implant in treatment of degenerative cervical spine disease.Methods:From January 2010 to December 2014,38 cases of cervical spondylosis patients were enrolled in our hospital,among them,23 cases were cervical spondylotic myelopathy,15 cases were nerve root type cervical spondylosis,21 cases were single segment,17 cases were two segment.They were treated with anterior segments,including 18 cases of dynamic cervical implant(DCI),20 cases of anterior cervical intervertebral disc resection and decompression and fusion(ACDF).There was no significant difference on age,course of disease,lesion segment and spinal cord compression(P0.05).The operative time,bleeding volume and complications were recorded.The pain was evaluated by VAS scores before operation and 6 months after operation.The nerve function recovery was evaluated by spinal cord function(Japanese Orthopaedic Association,JOA).The spinal canal decompression was measured by the image of cervical spinal canal sagittal diameter.Results:The mean follow-up time was 1.5 years(11 months to 24 months).There was no significant difference in improvement of pain and recovery of spinal nerve function between the DCI group and the conventional ACDF group(P0.05).But the change of activity of adjacent segments,DCI group was better than ACDF group(P0.05).Conclusion:Dynamic cervical implant has a good curative effect on degenerative cervical spine disease,which is equivalent to ACDF traditional operation,but more significant in reducing the incidence of the adjacent segment degeneration.
