Intrathecal prednisolone therapy in postoperative arachnoiditis following operation of herniated disc.

Fourteen patients with severe, chronic sciatica operated on repeatedly but without lasting success were treated by two intrathecal injections of methyl prednisolone (40 mg and 80 mg) at an interval of a few days. Significant improvement was obtained with regard to pain in many cases, but as there was no control series it is difficult to assess the results.
