[Indications for reoperation in radicular syndromes following surgical removal of lumbar disk hernias (author's transl)].

In case ischias-type pain persists or recurs following surgical removal of lumbar disk prolapses, it will be necessary to carefully weigh against one another as possible causes: disk prolapse recidivation, epidural or intradural cicatrization, and pseudoradicular pain in myotendinoses. Postoperative diskitis or spondylitis must also be considered as a possible cause.
