MIS Laminectomy

While conventional laminectomy and decompression are effective for neurological recovery, the Unilateral Laminectomy for Bilateral Decompression (ULBD) technique has emerged as a minimally invasive alternative. This approach aims to minimise iatrogenic injuries to paraspinal muscles and midline structures during spinal canal decompression. The ULBD technique, with a unilateral exposure and muscle retraction strategy, seeks to achieve spinal canal decompression while preserving the integrity of lumbar musculature. The surgical procedure involves a posterior midline or paramedian linear incision, thoracolumbar fascia incision, and ipsilateral paravertebral muscle retraction. A selected retractor facilitates unilateral access for decompression, determined by pathological findings and surgeon preference. This paper highlights the ULBD technique, emphasising its potential benefits in achieving decompression with reduced impact on lumbar musculature.
