Clinical Outcome of Fusion in Recurrent Herniated Lumbar Disc

Abstract

Background Data: Discectomy in recurrent lumbar disc herniation may not be an efficient treatment without fusion especially with prominent low back pain after primary surgery; therefore discectomy with fusion may be a good solution inrecurrent lumbar disc herniation. Purpose: The goal of this study was to focus on the efficacy of fusion in recurrentlumbar disc surgery. Study design: This study was carried out at different hospitals and the data was collected prospectively and retrospectively. Patients and methods: 50 patients (30 males and 20 females) underwent revisionsurgery following primary lumbar discectomy between 2009 and 2013. This study includes (50) patients with clinically and radiologically documented recurrentlumbar disc herniation scheduled for surgery. This includes (30) males and (20)females. All patients had a discectomy and postero-lateral fusion in re-operation. Patients’ age ranged from 25 years to 45 years with mean age 30 years. All patients in this study were presented with low back pain and recurrent radicular pain with mean duration of 21 months. Peri-operative assessments were carried using “Japanese Orthopedic Associationscore” (JOAs), and radiographic follow-up. Results: Follow-up ranged from 12-36 months with a mean follow-up 22.9 months; 25 patients had an excellent outcome, 20 patients had a good outcome, 3 patients had a fair outcome, and 2 patients had a poor outcome. Conclusion: Fusion surgery for recurrent lumbar disc herniation is effective and beneficial procedure. (2014ESJ062)
