Summary
Surgical discectomy offers faster sciatica relief for lumbar disc prolapse than conservative care. However, long-term effects on disc disease and other minimally invasive techniques require further study.
Area of Science:
- Neurosurgery
- Orthopedics
- Evidence-Based Medicine
Background:
- Lumbar disc prolapse is a common cause of low back disorders and a frequent indication for surgery.
- Despite its prevalence, scientific evidence supporting various surgical interventions remains limited.
Purpose of the Study:
- To systematically evaluate the efficacy and outcomes of surgical treatments for lumbar disc prolapse.
- To synthesize evidence from randomized controlled trials on surgical interventions for lumbar disc prolapse.
Main Methods:
- Conducted an updated Cochrane Review, analyzing randomized controlled trials (RCTs) and quasi-RCTs.
- Searched for all published RCTs up to January 1, 2007, adhering to standard Cochrane review methodology.
Main Results:
- Forty RCTs and 2 quasi-RCTs were included, focusing on chemonucleolysis, discectomy techniques, and epidural scar reduction.
- Discectomy showed better outcomes than chemonucleolysis, which was superior to placebo. Microdiscectomy yielded comparable results to standard discectomy.
- Limited evidence suggests interposition gels and fat grafts may reduce scarring, but clinical outcome data is scarce. Evidence for percutaneous techniques, laser, coblation, and transforaminal endoscopic discectomy is insufficient or inconclusive.
Conclusions:
- Surgical discectomy provides quicker relief for acute sciatica from lumbar disc prolapse compared to conservative management.
- Long-term effects of discectomy on the natural history of disc disease are unclear. Evidence for minimally invasive techniques is limited, with chemonucleolysis being an exception, though largely unavailable.
