    The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. [1] These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges . [ 1 ]

    Jaccoud arthropathy (JA), is a chronic non-erosive reversible joint disorder that may occur after repeated bouts of arthritis. [1] [2] It is caused by inflammation of the joint capsule and subsequent fibrotic retraction, causing ulnar deviation of the fingers, through metacarpophalangeal joint (MCP) subluxation, [1] [3] primarily of the ring and little-finger.
