[Surgical treatment of unstable, therapy-resistant and painful lumbosacral joints by distracting decompressive posterolateral spondylodesis over the divided sacral bar according to Zielke's method (author's transl)].

Here the procedure of the distracting decompressive fusion over the divided sacral bar which Zielke developed 8 years ago is being described. This procedure was applied in over 150 cases. In a follow-up only one pseudarthrosis was found in the area of L5/S1. 70% of the previously pensioned patients could at least be partially rehabilitated. 32 patients were asked of their opinion with a questionnaire. Only 2 patients (6%) assessed the operation results with "bad". Indication is in all instabilities of the lumbosacral joint. The problem of the multi-operated back can be largely solved through the possibilities of this procedure.
