Early Outcome of Sciatica after Redo Surgeries for Recurrent Lumbar Disc Herniation

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 study Patients 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 unsatisfactory results. 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)

A Consecutive Series of 39 Microendoscopic Discectomies for Recurrent Lumbar Disc Herniation

“…On the other side, according to a similar study by Alkosha et al, 2 for management of patients with RLDH using conventional open discectomy, the early outcome percentage of satisfactory results was 87%, this is also in close proximity to our fore mentioned results. In another study by Fu et al, 11 also using traditional open discectomy for RLDH on 41 patients, clinical outcome was excellent or good in 78.3% of patients.…”

Reperforming Minimally Invasive Microdiscectomy Approaches for Recurrent Lumbar Intervertebral Disc Prolapse

“…16,18,19 Alkosha et al, 2 reported similar results for their series of recurrent lumbar discectomy patients, with a mean preoperative sciatica VAS of (8.97±1.03) which improved to (2.55±1.64) at 90 days postoperatively. Dasenbroke et al, 6 also reported a mean preoperative sciatica VAS score of almost 7 which improved at long-term follow-up (1-2 years postoperatively) to a mean of 1.6 in both the MID and OD groups.…”
