Avascular Necrosis Picture
Avascular necrosis is a disease resulting from the temporary or permanent loss of the
blood supply to the bones. Without blood, the bone tissue dies and causes the bone to
collapse. If the process involves the bones near a joint, it often leads to collapse of
the joint surface. This disease also is known as osteonecrosis, aseptic necrosis, and
ischemic bone necrosis. |
