Discussion of Jaccoud's arthropathy
- Jaccoud's arthropathy is a chronic deformity characterized by ulnar deviation of the second to fifth fingers and subluxation of the metacarpophalangeal joints.
- Joint subluxations are voluntarily correctable by the patients.
- Toes may also be affected.
- Jaccoud's arthropathy may be seen in association with several rheumatic and non-rheumatic disorders, such as systemic lupus erythematosus, recurrent rheumatic fever, psoriatic arthritis, and inflammatory bowel disease arthritis.
