Zur Beurteilung der Myelogramme beim engen lumbalen spinalkanal

: The myelograms of 40 patients who had been operated on because of stenosis of the lumbar vertebral canal, were retrospectively assessed and measured. As was to be expected, the diameters were reduced, especially the sagittal diameter. Three configurations of the epidural space were seen representing different spatial capacities. The type occurring particularly often in lumbar osteogenic stenosis, which is conditioned by the patient's constitution, must be considered as a predisposing factor for the manifestation of a lumbar compression syndrome on account of its small capacity.
