Jaccoud arthropathy (JA), is a chronic non-erosive reversible joint disorder that may occur after repeated bouts of arthritis.
[1] It is commonly associated with systemic lupus erythematosus (SLE), and occurs in roughly 5% of all cases.
[3] Originally thought to be associated only with rheumatic fever, it has since been shown to occur also in SLE, Sjögren syndrome, scleroderma, dermatomyositis, psoriatic arthritis, vasculitis, ankylosing spondylitis, mixed connective tissue disease, and pyrophosphate deposition disease.
[2] There have also been cases of non-rheumatic JA associated with Lyme disease, HIV-infection and a number of other conditions.
[1] Plain hand radiographs typically show marked ulnar subluxation and deviation at the metacarpophalangeal joints.
