Facet joints connect the vertebral bodies to one another. They can also become arthritic and can be a source of back pain. The facet joints are located at the back of the spine and counterbalance the inter-vertebral discs. They help to keep the normal alignment of the spinal vertebrae and limit excessive motion. The pain and discomfort caused by degeneration and arthritis of this part of the spine is called facet arthropathy.
