Arthritic hand. Close-up of deformed hand due to rheumatoid arthritis. The knuckles (metacarpo phalangeal joints) are swollen and reddened and the fingers are curving away from the thumb. Heberden's nodes (lump of cartilage covered bone) on the terminal joints of the middle fingers indicate osteoarthritis. Rheumatoid arthritis is an autoimmune disorder (the body's immune system attacks body tissues); it attacks the joints, especially in the hands, feet, arms & hips. Affec- ted joints become swollen, red, painful & stiff. Treatment includes physiotherapy, corticosteriod drugs (anti-inflammatory, immunosuppressant),anti- rheumatoid drugs & joint replacement(arthroplasty).
