The Facet Joints are the joints behind the vertebra bone that connect the vertebra above and below. These joints allow for the vertebrae to slide on each other when bending the spine forward or backward. The joint surface has a cartilage on it that allows for smooth movement and produces a lubricant known a synovial fluid. There is a joint capsule, a strong ligament that holds the fluid and protects the joint, around every facet joint.
The vertebrae require movement to remain healthy and lubricated. This joint will remain healthy as long as each of the vertebrae are moving freely and aligned correctly. Loss of this movement is the beginning of a disease called “DJD”.
