title: Fibrous spinal stenosis. A report on 850 myelograms with a water-soluble contrast medium.
abstract: Although osseous spinal stenosis was rarely seen, fibrous spinal stenosis was demonstrated in 6% of 850 lumbar myelograms done with 10 ml doses of water-soluble Dimer-X (Maybaker). The common antecedents of fibrosis were myelography with an oily medium and spinal operations. In mild affections only the nerve root sheaths were obliterated. More severe fibrosis produced additional stenosis of a segment of the thecal sac.
