Jaccoud arthropathy
Medical condition
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.[3] Joints in the feet, knees and shoulders may also get affected.[1] It is commonly associated with systemic lupus erythematosus (SLE), and occurs in roughly 5% of all cases.[1][2]
When associated with rheumatic fever it is also called chronic post–RF arthropathy.[3]
