Abstract

Background Data: Result of redo discectomies varies widely in the literature. This may be due to variability in inclusion criteria and associated pathologies which may alter results. We tried to evaluate the early outcome of recurrent sciatica after redo discectomies in highly selected cases and risk factors for poor outcome. Purpose: to assess the rate of success of redo lumbar discectomy in patients with recurrent sciatica. Study Design: A retrospective clinical case studyPatients and Methods: A retrospective study including 30 cases with recurrent sciatica caused by true recurrent disc herniation over a period of 8 years. Clinical and radiological data were analyzed for proper selection and to exclude cases with associated pathologies. A Visual Analogue Scale was used to score pain severity before and after surgeries. Complications following redo surgeries were classified as minor and major. The outcome depended on pain relief and complications. Probable risk factors were recorded to detect those that might have contributed for unsatisfactoryresults. Results: Outcome was satisfactory in 20 cases, accepted in 6 cases and unsatisfactory in 4 cases. The overall improvement in sciatic pain after redo surgeries was comparable with that following primary surgery. We found diabetes the major risk factor for unsatisfactory results. Conclusion: Redo discectomy for recurrent sciatica proved to be of value and high rate of success when attempted in well-selected cases. (2014ESJ065)
