Anterior cervical decompression and autograft fusion with plate fixation for treating spondylotic cervical myelopathy(report of 32 cases) / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the clinical effect of anterior cervical decompression and autograft fusion with plate fixation on spondylotic cervical myelopathy.[Methods]From February 2002 to April 2008,32 cases of spondylotic cervical myelopathy were treated with anterior cervical decompression and autograft fusion with plate fixation.During the follow-up,the effect of fusion was observed for 12 months,complications were observed,and the results were evaluated by JOA.[Results]Thirty-two patients were followed up for 6～24months(15 months on average).Symptoms after operation were apparently found or cured.The JOA grade raised from 7～10 before operation(average 8.6) to 12～14(average 12.8) after treatment.The mean time for interbody fusion were 12 weeks,and its effective rate was 100 %.Cervical hematoma was found 3 hours postoperatively in 1 case,and symptom was relived after drainage treatment.Screw loosening was found after operation in another case,solid fusion of the fixation segment was achieved after external fixation for 6 months.[Conclusion]Spondylotic cervical myelopathy patients can be treated through the surgical method with anterior cervical decompression and autograft fusion with plate fixation.The method can release the anterior pressure on the spinal cord,and significantly increase the rate of interbody fusion.
