[The value of pneumomyelography in the investigation of the terminal theca (author's transl)].

Three hundred lumbar air myelograms were selected from a total of 1,500 examinations and their results analysed. The method described in this paper provides significantly more information than conventional myelograms. In the opinion of the author, lumbar air myelography can replace iodinated oils and esters in the diagnosis of disc prolapse, since its accuracy is not significantly inferior. Because of its lack of toxicity it is to be preferred.
