Thoracic myelopathy is very rare condition. We experienced 6 cases of this condition, namely a case of ossification of the posterior longitudinal ligament of thoracic spine, a case of 8th thoracic intervertebral disc herniation, a case of ankylosing spondylitis, and a case of ossification of the yellow ligament from eighth to eleventh thoracic vertebra.According to myelographic block laminectomy was carried out in all cases, including nucleotomy for disc herniation and extirpation of ossified ligament.The operative results are satisfactory in 3 cases, the other 3 cases are fair. The operative results showed that extent of laminectomy is most responsible for relieve the symptoms.
