Facet joint syndrome is an arthritis-like condition that affects the spine distinguished by inflammation and degeneration.The facet joints provide mobility and flexibility in the spine. Each vertebra in the spine has two facet joint sets. Each joint is surrounded by connective tissue that essentially acts as a capsule. The connective tissue produces fluid to lubricate and nourish the joint. In the case of facet joint syndrome, the bones that make up the joints do not have enough cartilage to allow for smooth movement. This may result in result in back pain and/or stiffness after periods of inactivity.
