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 = having to do with the spine. Arteriovenous = having to do with arteries and veins. Malformation = a congenital (present at birth) deformity. A spinal arteriovenous malformation (spinal AVM) is an abnormal tangle of blood vessels in the spinal cord. The two types of major blood vessels in the body are arteries and veins. Arteries carry oxygen-rich blood to the bodyâs tissues, and veins bring oxygen-depleted blood back to the heart and lungs. Arteries are usually under high pressure, since the blood inside these vessels has recently been pumped forcefully from the heart.
