| ABSTRACT |
|
Twenty-two surgical cases of myelopathy due to narrow thoracic spinal canal associated with degenerative changes of the posterior spinal elements have ever been reported in the literature since Govoni presented the first cases in 1971. Authors have experienced five surgical cases and added them to the above twenty-two cases. And clinical analysis was made with twenty-one cases, which had proper data to be analysed and included our own five cases. Thirteen patients were male and the average age was around fifty-five years.
Most of the lesions were found in the lower thoracic spines and involved single segment in each patient. The symptoms were so various and non-specific that pertinent treatments were delayed and the disease had been misdiagnosed in most of the patients. Intrathecal enhanced spine CT might be most accurate diagnostic tool. Surgical decompression may proceed good results, even when symptoms have been presented for years. |
