Osteoma osteoide: causa poco frecuente de dolor crónico en la muñeca en una niña / Osteoid osteoma: unusual cause of chronic pain in the wrist in a child

El osteoma osteoide es una lesión ósea benigna que, habitualmente, se acompaña de clínica típica caracterizada por dolor nocturno que mejora con antiinflamatorios no esteroideos. Aunque la presentación clínica es típica, con frecuencia, es común la demora diagnóstica, en especial, en los casos con localización atípica.Se presenta el caso de una paciente de 10 años con dolor en la muñeca izquierda de dos años de evolución con diagnóstico de osteoma osteoide localizado en el hueso grande del carpo. La localización atípica de la lesión conllevó un retraso diagnóstico importante

Osteoid osteoma is a benign bone lesion that is usually accompanied by a typical clinical condition characterized by night pain that improves with non-steroidal anti-inflammatory drugs. Although the clinical presentation is frequently typical, diagnostic delay is common, especially in cases with an atypical location.We report the case of a 10-year-old patient with left wrist pain of two years of evolution with diagnosis of osteoid osteoma located in capitate bone. The atypical location of the lesion led to a significant diagnostic delay.

Stress Fracture of the Capitate

Most capitate fractures occur in association with additional carpal injuries, particularly scaphoid fractures. Isolated fractures of the capitate account for only 0.3% of carpal injuries, and stress fractures are one form of this fracture. We report the case of a 20-year-old male who had a stress fracture of the capitate after serving as an honor guard in the military. Conventional radiographs and computed tomography of the right wrist revealed a minimally displaced fracture line located at the midcarpal aspect of the right capitate. A magnetic resonance imaging scan demonstrates a subarticular capitate fracture with diffuse bone marrow edema, small osteophytes, and irregularity of the midcarpal articular cartilage. We also review the carpal kinematics which possibly caused the stress fracture. Although stress fractures of the capitate are rare, they should also be accounted for with patients who perform repetitive motions of the wrist to a considerable extent.

Osteoid Osteoma of the Capitate with Extensor Tenosynovitis

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.
