What Is a Lumbar Laminectomy? A lumbar laminectomy is a surgical procedure to remove a small portion of a vertebra, or back bone in the lower back (lumbar). Lumbar laminectomy is usually done to take pressure off the spinal cord or a spinal nerve. It may also be done to access the spinal cord, bones and discs below the lamina, or the removed part of the bone.
