Spontaneous flexor tendon rupture in systemic lupus erythematosus: A case report

Spontaneous flexor tendon rupture is an unusual complication of systemic lupus erythematosus (SLE) and has not previously been reported. While tendon ruptures in association with SLE have been focused on the previous studies, upper extremity tendon ruptures are infrequently reported in the literature. Here, we present an uncommon case of spontaneous flexor tendon rupture of the ring and little fingers in a patient with SLE and discuss the mechanism of injury and its surgical treatment.
