A laminectomy is the removal of part of the vertebral lamina, the bony arch on the dorsal surface. The surgery is done to relieve pressure on the nerves. A spinal fusion is the insertion of a wedge-shaped piece of bone or bone chips between the vertebrae to stabilize them. A spinal fusion may also be done by placing a hollow titanium cylinder within the spine. Foraminotomy is a surgical procedure to enlarge the space where a spinal nerve exits the spinal canal.
