Osteoarthritis is degenerative arthritis that can cause a breakdown of the cartilage between the facet joints of the spine.

Facet joints are the places where the posterior parts of the bones in your spine (vertebrae) touch each other, and there are little bits of cartilage at the points of contact. When the cartilage is broken down, there is more friction with movement.

What causes it?

This is a degenerative condition that occurs with age.

What does it feel like?

During the early part of the day, the pain may be lessened due to the buildup of fluid in the joints. As more stress is applied to the spine and its joints throughout the day, pain may increase by the evening. The pain may be localized around one joint/vertebra or several levels -- for example, the entire lower back may be painful.

How do I know if I have it?

X-rays and a physical exam will show your doctor if there is any deterioration in the joints.

How is this treated?

1. Conservative treatment is the first step. This may include anti-inflammatory medicines, such as ibuprofen, and physical therapy. Stretching exercises for the hamstrings, hip joints, and back may be helpful, as well as water therapy, which provides a nearly weightless environment for exercise.
2. Steroid injections (called facet injections) may also be used to relieve the pain of osteoarthritis if the conservative treatment proves ineffective.
3. A spinal fusion may be used to treat this condition. This surgery involves placing a piece of bone at the back of the spine which, when healed, will fuse two or more vertebrae together. This stabilizes the spine and eliminates movement at the painful joints. Metal rods and screws may be used to hold the vertebrae in place.
