Abstract
Osteoarthritis of the hand is common, frequently affecting postmenopausal women. Heberden's nodes are characteristic lesions. The present case is a 62 year old female having pain and functional impairment of her right thumb. She was examined by musculoskeletal ultrasound, which played a useful role in diagnosing the cause of pain and functional impairment.
