A surgical procedure to join two or more spinal vertebrae permanently is called spinal fusion.
A bone like material is placed between two vertebrae which may be secured with plates, screws & rods so that they can heal into one unit. It mimics the normal healing process of a broken bone. It immobilizes those parts of the spine. Hence can lead to additional stress & strain on the vertebrae above & below the fused portion.
