A column of bones called vertebrae make up your spine. Fusing or joining together two or more vertebrae is called spinal fusion.

A piece of bone, often taken from the pelvis, is added to the space between the vertebrae to join them together. Rods, plates, wires, or screws may be attached to prevent the bones from moving while the spinal fusion heals.
