title: Osteoid osteoma of the trapezium. First case report of roentgenographically demonstrated progression in the trapezium.
abstract: Osteoid osteoma in the trapezium seems not to have been reported previously. This occurred in a 16-year-old boy who had complete and instant relief of pain following excision. There was progression of the lesion from roentgenographically normal appearing bone to bone with typical changes of osteoid osteoma.
