Osteoid osteoma of the capitate: A case report

Osteoid osteoma is a benign relatively uncommon osteogenic tumour of unknown aetiology, affecting mainly the long bones and rarely the carpal bones. Because of its nonspecific presentation in the wrist, it remains a diagnostic challenge. We report an unusual case of osteoid osteoma of capitate in a 15year old school going girl where it presented as chronic nagging nocturnal pain and weakness of hand. Diagnosis was made by MRI scan of the wrist and surgical excision lead to a dramatic relief of symptoms.
