Osteoid Osteoma of the Capitate with Extensor Tenosynovitis

ABSTRACT

An osteoid osteoma is a benign bone tumor. It is most commonly found in the femur and tibia but only 5% to 15% occurs in hand. Osteoid osteoma of carpal bone has vague nature of symptoms including spontaneous dull aching causing delayed diagnosis and the late treatment. We had a patient with an osteoid osteoma of the capitate bone presenting with tenosynovitis. We present clinical and radiological findings including magnetic resonance imaging, surgical result, and a review of the current literature.
