Osteoid osteoma of the hamate bone. Case report and review of the literature.

Osteoid osteoma is rarely located in the hamate. Only five similar cases have appeared in the international literature, and none have appeared in the Spanish literature. In a 15-year-old girl, the lesion was excised en bloc, and the defect was filled with a bone graft. Two and one-half years after the operation the patient was asymptomatic with normal mobility of the affected wrist.
