 Definition/Description[edit | edit source]

avascular necrosis (also known as; osteonecrosis, bone infarction, aseptic necrosis, ischemic bone necrosis and AVN) is a condition where bone tissue dies due to a lack of blood supply. This decrease in blood supply causes a decrease in oxygen and nutrition delivery to the bone, which leads to multiple breaks in the bone and eventual collapse of the affected bone.
