Nineteen hundred and thirty four marked a turning point in the history of the understanding of sciatica when Mixter and Barr’s paper on rupture of the intervertebral disc was published in the New England Journal of Medicine. In 1927 Putti had drawn attention to the importance of facet osteoarthritis as a cause of sciatica. His work was overshadowed by the impact of the description of prolapse of the intervertebral disc. Indeed the entity of prolapsed disc soon emerged as the only intervertebral disc lesion which was considered in dealing with the clinical problems of sciatica.
