Implication

A systematic review compares outcomes of unilateral biportal decompression in lumbar stenosis, suggesting it may offer modest benefits over other methods.

Key Points

  • This review aims to evaluate the effectiveness and safety of unilateral biportal endoscopic decompression versus other endoscopic techniques for lumbar spinal stenosis.
  • Conducted a systematic review and meta-analysis of clinical studies comparing UBE with tubular and uniportal decompression.
  • Included pooled analyses for predefined outcomes and comparator-specific analyses.
  • Assessed outcomes like complications, ODI, and changes in dural sac area.
  • Patients in the unilateral biportal endoscopic decompression group had lower overall complications and fewer dural tear events.
  • UBE showed lower ODI and pain scores at follow-up, although benefits varied.
  • Dural sac cross-sectional area improvements favored UBE with low to moderate variability.
