Synonyms: Idiopathic AVN
A rare osteonecrosis characterized by bone necrosis due to disrupted blood supply in the absence of a known cause. Affected bones include the femoral head talus vertebral body humerus and scaphoid among others.

If left untreated the condition may progress to bone collapse with secondary degeneration fragmentation and pathological fracture as well as osteoarthritis.
