This condition is a deterioration of the facet joints, which help stabilize the spine and limit excessive motion. The facet joints are lined with cartilage and are surrounded by a lubricating capsule that enables the vertebrae to bend and twist.
Pain from facet joint syndrome differs depending on which region of the spine is damaged. If the cervical, or upper spine is affected, pain may be felt in the neck, shoulders, and upper or middle back. The person may also experience headaches.
If the lumbar, or lower spine, is affected pain may be felt in the lower back, buttocks and back of the thigh.
Facet joint syndrome occurs when the facet joints become stressed and damaged. This damage can occur from everyday wear and tear, injury to the back or neck or because of degeneration of an intervertebral disc. The cartilage that covers the stressed facet joints gradually wears away. The joints become swollen and stiff. The vertebral bones rub directly against each other, which can lead to the growth of bone spurs along the edges of the facet joints.
