Spinal Fusion. Spinal fusion is a surgical procedure used to correct problems with the small bones of the spine (vertebrae). It is essentially a welding process. The basic idea is to fuse together the painful vertebrae so that they heal into a single, solid bone.ll spinal fusions use some type of bone material, called a bone graft, to help promote the fusion. Generally, small pieces of bone are placed into the space between the vertebrae to be fused. A bone graft is primarily used to stimulate bone healing.
Spinal fusion is the surgical joining of two vertebrae in your neck or back. Your vertebrae are the bones that make up your spine (backbone). Spinal fusion permanently stops movement between two or more vertebrae. It is a treatment for a variety of diseases and conditions of your spine. All spinal fusions use a bone graft to fuse or join two vertebrae. Sometimes your doctor will also use screws, rods or plates to hold your vertebrae in place.
