Laminectomy

Spinal stenosis is a narrowing of the bony canal in the lower back through which the spinal cord and spinal nerves run. Severe narrowing results in pain and weakness in the back and legs. Laminectomy is the most common type of surgery used to treat stenosis. It is the removal the removal of the lamina, a portion of a vertebra (one of the bones of the back), to make room for the nerves. Foraminotomy is an expansion of the area in a vertebra through which nerves exit the backbone.
