Objectives: A retrospective study of patients undergoing second operation after initial lumbar discectomy, to investigate the reasons associated.

Methods: In a period of three years a total number of 30 patients had a reoperation after lumbar discectomy. The initial operation performed before one month to five years. There is a evaluation of intraoperative findings and of a short period of follow up. Data were obtained from Spine Unit of Errikos Dunan Hospital.

Results: Among 30 patients, 60% were recurrent disc herniations, 18% were fusions and 22% were decompressions. The follow up is from two months to three years for 25 patients, 4 patients had further spinal surgery. Very satisfied, satisfied were 80% of patients.

Conclusion: Although reoperation after lumbar discectomy is uncommon, it is very possible to face it because of the increasing number of initial discectomies performed.
