Significance of Functional Myelography of the Lumbar subarachinoideal Space

Abstract

Two kind of water soluble contrast media “Mgl. iothalamate” and “Mgl. iocarmate” were used for standing functional myelography of the lumbar spine.
Twenty-seven patients, aged from 19 to 64, complained of low back pain and of radiating pain to the leg, were diagnosed lumbar disc protrusion in 18 cases, thickening of the lig. flava in 5 cases, spinal canal stenosis in 2 cases, and others.
Almost all of the three diseases revealed distinct change of myelographic findings.
As narrowing of the column of the contrast medium was observed at the level of disc and facet, significant informations were obtained by comparison of sagital diameter at this level to those of adjacent vertebral body in position of standing flexion and extension of the spine.
