This randomized controlled trial compared the efficacy of unilateral endoscopic (UE) and unilateral biportal endoscopic (UBE) techniques for unilateral laminotomy for bilateral decompression in 60 patients with lumbar spinal stenosis. Both techniques resulted in significant reductions in pain and disability scores at 3 and 6 months postoperatively, with no significant differences in outcomes between the groups.
Key findings
- Both UE-ULBD and UBE-ULBD groups showed significant reductions in VAS and ODI scores at 3 and 6 months postoperatively (P<0.05).
- At 6 months, all SSS dimension scores improved significantly in both groups (P<0.05).
- The modified MacNab excellent-to-good rates were 93.33% for UBE-ULBD and 90% for UE-ULBD, with no significant difference (P>0.05).
Why it matters
Understanding the comparative efficacy of UE and UBE techniques for lumbar spinal stenosis can guide surgical decision-making, ensuring that patients receive effective minimally invasive treatment options with similar outcomes.
