Artropatía de Jaccoud: algo más que lupus

Jaccoud's arthropathy (JA) occurs in 5% of patients with systemic lupus erythematosus and causes deformities in the hands and feet due to intermittent inflammation of the periarticular soft tissues, including tendons and joint capsules. These deformities include subluxation of the metacarpophalangeal joints, ulnar deviation of the 2nd to 5th fingers, swan neck deformities, Z deformity of the thumb, hallux valgus, subluxation of the metatarsophalangeal joints and other, non-erosive subluxations. In the early stages of the disease, these deformities are reversible but become irreversible in the long-term and usually require surgical correction. The clinical management of JA is always aimed at early control of joint inflammation and preventing severe limitation of movement and persistent loss of joint function.
