Arthritic hand. Coloured X-ray of the deformed hand of a patient suffering from rheumatoid arthritis. The patient's fingers are abnormally bent because of damage to the joints (pink). Rheumatoid arthritis is an autoimmune disorder. It occurs when the body's immune system attacks joint tissue, commonly in the hands and feet. Affected joints become inflamed and painful, limiting movement. There is no cure for the disease, but anti-inflammatory drugs and immunosuppressants may relieve the symptoms. Physiotherapy can help to keep the joints supple, and special tools may compensate for the lack of mobility.
