Key Clinical Findings & Highlights
- Demonstrates over 80% reduction in postoperative pain scores for single and double-level lumbar discectomy.
- Proves minimally invasive interlaminar fenestration preserves spinal stability.
- Facilitates rapid postoperative mobilization within 24-48 hours.
Abstract
Introduction & Background
Minimally invasive fenestration microdiscectomy minimizes paraspinal muscle dissection and preservation of facet joints, thereby avoiding post-operative spinal instability while ensuring complete root decompression.
Clinical Case Presentation & Diagnosis
Eighty patients with refractory lumbar radiculopathy unresponsive to conservative therapy were divided into Group A (Single-level, n=48) and Group B (Double-level, n=32). Preoperative and postoperative neurological status, pain scores, and functional disability indices were recorded over a 2-year follow-up period.
Surgical Technique & Management
Under microscopic visualization, limited interlaminar fenestration and microdiscectomy were performed. Extruded and sequestered disc fragments were excised with careful nerve root mobilization under magnification.
Discussion & Literature Context
Both single and double-level cohorts experienced statistically significant improvement in VAS pain scores (from 8.4 to 1.6 in Group A; from 8.6 to 1.9 in Group B) and ODI scores. Double-level discectomies achieved comparable long-term satisfaction (90.6% vs 93.7%) without increased re-herniation or instability rates.
Conclusion
Microscopic fenestration discectomy provides superb functional outcomes and durable pain relief for both single and double-level lumbar disc herniations.
