These joints contribute to the incredible range of motion that the spine enjoys. This includes twisting as well as flexion and extension. With aging or with trauma, the facet joints are prone to cartilage degeneration and arthritis just like other joints such as the knee or hip causing pain. Facet joint injections of steroid medications are often given to patients with this type of pain. The injections not only provide pain relief, but they can also help the physician pinpoint exactly where the pain originates and can confirm or reject the facet joints as the source of the pain.
