Facet joints are small joints between the vertebrae of the spine that provide stability and flexibility. When these joints become inflamed or degenerate, they can cause localized back or neck pain, sometimes radiating into the buttocks or shoulders.
Facet joint pain is a common cause of chronic spinal pain. Treatments range from physiotherapy and injections to minimally invasive procedures such as pulsed radiofrequency (PRF) applied to the medial branch nerves that supply the joints.
