title: [Complex indications in surgery of the lumbar spinal canal].
abstract: Opinions on the treatment of disc herniation are very controversial and the results reported vary, very much indeed. Most often, one decided--and still decides--to excise the disc herniation in conjunction with hemilaminotomy or flavectomy; this method having been carried out from 1974 to 1983 on 598 patients, at the department of Orthopaedic Surgery, Balgrist, of the University of Zurich. A follow-up of over 400 patients has proved to be very informative: whereas very good or good clinical results can be reported in 73.6% of such cases with disc herniation, alone, these not having undergone operation before, similar results were only found in 27.2% of those who had also been suffering from additional causes of lumbalgia like a relatively narrow spinal canal, spondylolisthesis, spondylolysis or nearthrosis for instance. This finding is of paramount importance when attempting to improve the overall results. It is very necessary to separate the complex cases from the "simple" disc herniation ones. At the same time, those patients suffering from lumbalgia due not only to a herniated disc but also to other additional causes arising from alterations to the lumbar spinal canal must be judged and treated differentially. The present follow-up permits conclusions and considerations correspondingly.
