What Do Disc Repair and Laminectomy Involve?
• General or spinal anesthesia can be used. First, the back is approached through a two-inch to five-inch long incision in the midline of the back and the left and right back muscles (erector spinae) are dissected off the lamina on both sides and at multiple levels. • After the spine is approached, the lamina is removed (laminectomy) which allows visualization of the nerve roots. • The facet joints, which are directly over the nerve roots, may then be undercut (trimmed) to give the nerve roots more room.
