What is avascular necrosis

HEYA!!

Explanation:

Avascular necrosis is basically the death of bone tissue due to a lack of blood supply. Also known as osteonecrosis, it can lead to tiny breaks in the bone and the bone's eventual collapse. A broken bone or dislocated joint can interrupt the blood flow to a section of bone.
