Abstract
We report on the case of bilateral avascular osteonecrosis (AVN) of the lunate and triquetrum in a 45-year-old woman without any relevant medical history for which the cause could not be established. She was treated conservatively with splinting and analgesics. The patient was able to pursue her work and hobbies with subnormal range of motion at 1-year follow-up. AVN of the triquetrum is very rare, as it is a richly vascularized bone. The presence of AVN in multiple carpal bones has only been described in patients receiving high doses of corticosteroids. To our knowledge, there are no other cases of idiopathic AVN of multiple carpal bones in the literature.
