A Decompressive Lumbar Laminectomy is one of the most common procedures for spinal stenosis. The surgeon will begin by making an incision in the mid-line of the back. After exposing the area they will then cut away bone (the lamina), bone spurs, and ligaments that are compressing nerves. This is referred to as decompression. The surgery can take anywhere from 30 min to an hour depending on the severity of the compression on the nerve roots. The patient is able to go home the same day.
