This document describes a unilateral laminectomy bilateral decompression (ULBD) procedure performed on a 72-year-old woman for right buttock pain and low back pain. It provides background on ULBD and discusses relevant studies showing ULBD results in shorter hospital stays, faster mobilization, and less need for opiates compared to open laminectomy. The document outlines the surgical steps of the ULBD procedure, including positioning the patient prone, making unilateral bone removals while protecting the dura and ligaments, and fully decompressing the spinal canal bilaterally. It notes some pitfalls and complications of ULBD and emphasizes the importance of adequate but limited bone removal.
