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.
Lumbar spinal fusion is surgery to join, or fuse, two or more vertebrae in the low back. Spinal fusion is major surgery, usually lasting several hours.
