Abstract |
Background |
Minimally invasive techniques for lumbar spinal stenosis (LSS) aim to reduce soft-tissue injury while achieving adequate neural decompression. Traditional open decompression remains effective but is associated with extensive muscle dissection and prolonged recovery. Although the Quadrant retractor system is commonly used in transforaminal lumbar interbody fusion (TLIF), its application for non-fusion decompression has been seldom reported [ 1 ].
Objective |
To describe a reproducible, muscle-sparing decompression technique using the Quadrant system for central and lateral recess stenosis without instrumentation or fusion. Technique Summary: Through a paramedian Wiltse approach and a 4–5 cm vertical incision, the Quadrant retractor is docked on the facet-laminar junction [ 1 , 2 ]. Microscopic decompression is performed including ipsilateral laminotomy, medial facetectomy, and undercutting of the contralateral side. The technique preserves midline structures and avoids unnecessary tissue trauma [ 2 , 3 ].
Conclusion |
The Quadrant-assisted decompression technique offers a safe, efficient, and minimally invasive alternative to conventional laminectomy for LSS in appropriately selected patients [ 9 ].
