Spinal fusion is a surgical procedure used to correct problems with the small bones in the spine (vertebrae). It is essentially a “welding” process. The basic idea is to fuse together two or more vertebrae so that they heal into a single, solid bone.
Spinal fusion is surgery to permanently connect two or more vertebrae in your spine, eliminating motion between them. Spinal fusion involves techniques designed to mimic the normal healing process of broken bones. During spinal fusion, your surgeon places bone or a bone-like material within the space between two spinal vertebrae. Metal plates, screws, and rods may be used to hold the vertebrae together, so they can heal into one solid unit.
Because spinal fusion surgery immobilizes parts of your spine, it changes the way your spine can move. This places additional stress and strain on the vertebrae above and below the fused portion and may increase the rate at which those areas of your spine degenerate.
