Avascular necrosis is a medical condition that occurs when the blood supply to a bone is reduced or interrupted. Without an adequate supply of blood, the tissue in the bone dies. As a result, tiny breaks in the bone occur, which can lead to the eventual collapse of the bone. If avascular necrosis develops in a bone near a joint, the joint surface may also collapse. Although this condition can occur in any bone, it most often affects the ends of long bones, such as the end of the femur (where it connects to the hip). Avascular necrosis is also referred to as ischemic bone necrosis, aseptic necrosis and osteonecrosis.
