A report is made in 6 cases of thoracic spondylotic myelopathy. Their age ranges from 28 years to 68 years old. Of them two cases are male and 4 are female. Generally the site of this disease is said to be most frequent at the lower thoracic vertebra, but this myelopathy can be also observed in the upper thoracic vertebra. As for the clinical symptoms sensory disturbances of the legs, disturbances of movement, and rectovesical disturbances can be pointed out, that gradually progress in some cases, while in others this myelopathy is induced by sternomutator or by fall, that aggravates by degree. X-ray picture reveal the narrowing of the inervertebral disc space, the calcification of inervetebral disc and sclerosis of the posterior margin of vertebral body in some cases, but these changes seem to be aging phenomena, that cannot at once be concsidered necessarily as the direct cause of myelopathy. There are cases where no abnomality of humoral findings, that symptoms are not always consistent. At the present stage myeography is most useful for the diagnosis. As long as the case be definititly diagnosed as myelopathy due to the disturbance of intervertebral disc, anterior decompression proves to be most rational, but there are cases difficult of diagnosis. We have performed laminectomy in five cases and obtained favorable results in all of them.
