Transdural Discectomy Lumbar Region: A retrospective series of 10 cases

Abstract

Over the past Ten years more than 500 Lumbar discectomies have been performed by the senior author through all standard methods, but only ten patients underwent Transdural disc excision. Seven males and three females in age group of 18 58 yrs were treated by this method. Six patients had PIVD at L4-L5 level, 3 at L5-S1 and one patient had PIVD at two levels L2-L3 and L3-L4.Results were evaluated by postoperative Frankel’s grading, relief from pain, sensory improvement, return of bowel and bladder functions and complications. We achieved excellent results as for as relief of sciatica was concerned. Full recovery in motor and sensory symptoms was observed in 80% (n = 8) cases. One patient of cauda-equina syndrome did not recover and one patient developed headache due to CSF leak.
