Osteoid osteoma of the carpus. Case reports and a review of the literature.

Osteoid osteoma mainly affects long bones, and is rarely observed at the hand. The authors report three cases of osteoid osteoma in the carpus (one case in the scaphoid, one in the triquetral, one in the capitate), treated by removal of the entire nidus. No bone grafting or intercarpal arthrodesis was necessary. There were no recurrences.
