A comparative analysis of the outcome of unilateral laminotomy and conventional laminectomy in patients with single-level degenerative lumbar spondylolisthesis: a single-center retrospective study 104 patients on postoperative pain and functional dis

Both unilateral laminotomy and conventional laminectomy provide effective pain relief and adequate decompression for spinal stenosis. Unilateral laminotomy offers the advantage of reduce blood loss, shorter operative time, and lower VAS scores for back pain. Radiographically, the two procedures produce similar outcomes in terms of translational motion and disc height, although the traditional laminectomy group exhibited a larger epidural cross-sectional area. Despite this, VAS scores for leg pain were comparable between the two groups. Further studies are needed to compare the effects of surgical techniques at different lumbar levels.
