Comparison of Myelographic Findings Before and After Surgery in Cervical Osteochondrosis

Abstract

The preoperative myelographic findings of 131 patients operated for cervical osteochondrosis (105 operated by anterior fusion, 24 by laminectomy and 8 by foraminotomy) were compared with postoperative myelographic findings.There is generally a satisfactory correlation between the postoperative myelographic findings and the improvement of the clinical status of these patients.Both anterior fusior and laminectomy showed excellent or good improvement (more than 80%) of postoperative myelographic findings. It is necessary for getting satisfactory findings of post-operative myelography in anterior fusion to remove the posterior osteophytes and to correct alignment of the cervical spine.
