Swan neck deformity is an abnormal positioning of the joints in your fingers. It’s named because of the way an affected finger bends, giving it a curved appearance similar to the neck of a swan.The deformity can be caused by trauma or injury to the finger, as well as by diseases that attack the joints of the fingers, such as rheumatoid arthritis (RA).
