Spinal fusion is a surgical procedure which is performed to correct problems related to the small bones of the spine (vertebrae). This technique principally follows the welding process. That is it requires to simply fuse together the painful vertebrae, so that the healing results in a single, solid bone.

In a spinal fusion, the surgeon takes the spine with its many moveable vertebra and transforms it into one long solid column with no movement.
