Bilateral rupture of the extensor pollicis longus tendon. A case report.

Abstract Bilateral rupture of the extensor pollicis longus (EPL) is a rare entity and the few cases that have been reported were associated with an underlying systemic condition such as rheumatoid arthritis or following an injury. We present the case of a patient who was referred to us with a spontaneous rupture of the EPL tendon of the right wrist and that of the left side observed 2 months after tenosynovectomy. The patient had not any pathologic condition or evidence of trauma in both wrists. In the left side, he was operated on and a tenolysis and subcutaneous tendon transposition was performed. Despite this preventive surgery, the patient suffered from a tendon rupture. The possible causes of surgery failure are discussed.
