Spinal stenosis subsequent to juvenile lumbar osteochondrosis.
This paper describes eight patients with spinal stenosis associated with marked osteochondrous changes in the vertebral bodies due to juvenile lumbar osteochondrosis (Scheuermann's disease). In no case was the midsagittal or interpedicular diameter of the spinal canal indicative of bony stenosis. On the other hand, in the myelograms the sagittal diameter of the dural sac was in all cases significantly narrowed, a diagnostic sign of central spinal stenosis. Therefore, myelography should always be contemplated when osteochondrous changes are present and spinal stenosis is suspected clinically regardless of whether the spinal canal diameters are normal in plain films.
