Abstract

We present a rare case of spontaneous tendon rupture of the extensor digitorum communis (EDC) in a patient with systemic lupus erythematosus (SLE). Inflammation in SLE presents as periarthritis, which may develop into Jaccoud’s arthropathy. We bridged the ruptured tendon of the EDC (III) at the metacarpophalangeal (MP) joint of this patient with a tendon graft. This case demonstrates that this portion of the MP joint can be a site of tendon rupture of fingers in SLE patients.
