A result of rheumatoid destruction of the extensor tendon mechanism at the PIP joint and also secondary to trauma without arthritis. Can be moderate to severe and indicates that a separate classification system exists. Swan-neck deformity consists of hyperextension of the proximal interphalangeal (PIP) joint, flexion of the distal interphalangeal (DIP) joint, and sometimes flexion of the metacarpophalangeal (MCP) joint.
