Avascular necrosis, also known as osteonecrosis, is a condition that occurs when blood supply to a bone is disrupted, causing the bone tissue to die. This can lead to bone collapse, arthritis, and other complications. Avascular necrosis can occur in any bone in the body, but it most commonly affects the hips, knees, shoulders, and ankles.
