Facet osteoarthritis, also known as facet joint arthritis or facet joint osteoarthritis, is a degenerative joint condition that affects the facet joints of the spine. The facet joints are small joints located on either side of each vertebra that connect the bones of the spine and help to facilitate movement.
Facet osteoarthritis occurs when the cartilage in the facet joints breaks down and wears away over time, causing the bones to rub against each other. This can lead to inflammation, pain, stiffness, and decreased mobility in the affected area of the spine.
Facet osteoarthritis is most commonly seen in the lower back (lumbar spine) or the neck (cervical spine) and is often associated with age-related degeneration of the spine. Other risk factors for facet osteoarthritis include obesity, a sedentary lifestyle, and previous injuries or trauma to the spine.
Treatment for facet osteoarthritis may include medication, physical therapy, joint injections, or surgery in severe cases. The goal of treatment is to reduce pain, improve function, and prevent further degeneration of the affected joints.
