Spine Fusion
Spinal fusion eliminates motion between vertebrae. It also prevents the stretching of nerves and surrounding ligaments and muscles. It is an option when motion is the source of pain, such as movement that occurs in a part of the spine that is arthritic or unstable due to injury, disease, or the normal aging process. The theory is if the painful vertebrae do not move, they should not hurt. Fusion will take away some spinal flexibility, but most spinal fusions involve only small segments of the spine and do not limit motion very much.
