Osteoid osteoma is a benign bone tumor that rarely localizes in the hand or
the carpal bones. We report two cases of osteoid osteoma localized in two
different carpal banes. Unremitting wrist pain was a major clinical symptom
. Surgical treatment including excision of the nidus was dramatically curat
ive. In young patients, osteoid osteoma should be considered in the differe
ntial diagnosis of chronic wrist pain.
