Pseudoclaudication in lumbar disc protrusions. Contribution in understanding the etio-pathogenetic factors of the syndrome and surgical results in eight cases.
Eight cases of pseudoclaudication in patients with herniated lumbar discs are reported. Clinical features and variations in clinical patterns are briefly described. The hypotheses concerning the mechanisms causing pseudoclaudication, formulated by some authors, are discussed. It is suggested that this particular syndrome might be related to an arrangement of the spinal circulation with one lumbar or sacral accessory artery playing an important role in supplying the lower portion of the spinal cord.
