Is Avn a Disease?

Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. When blood supply is cut off, the bone tissue dies and the bone collapses. If avascular necrosis happens near a joint, the joint surface may collapse. This condition may happen in any bone.

Is avascular necrosis serious?

Avascular necrosis is a localized death of bone as a result of local injury (trauma), drug side effects, or disease. This is a serious condition because the dead areas of bone do not function normally, are weakened, and can collapse.

Is AVN an autoimmune disease?
