Abstract
The neurological findings tend to be aggravated, according to severity of for lumbar spinal canal stenosis. We sometimes experience the case that the level of the stenosis on the image does not correspond with neurological findings. The cause is thought to be the specific anatomical structure of the lumbar dural tube which is an aggregate of nerve roots.The purpose of the current study was to evaluate the discrepancy of responsible level for neurological findings between image findings retrospectively. We selected 38cases with operative severe spinal canal stenosis which presented total block or subtotal block by myelogram. The comparison and analysis between the responsible level of neurological findings and image findings were performed the discrepancy between neurological and image findings were noted with 13 cases (34.2%), and most of them were L3/4 stenosis accompanied with L5 disorder. The result was thought to be important clinically.
