SLE arthropathy is rarely erosive or deforming. Characteristic hand deformities are swan neck deformities that result from recurrent synovitis and inflammation of the joint capsule, tendons, and ligaments. These deformities are usually reducible and nonerosive (resembling Jaccoud arthropathy, which is a nonerosive arthritis following acute rheumatic fever).
