Avascular Necrosis- Health Encyclopedia and Reference |
 | | Avascular necrosis (of bone) is deterioration of bone due to a diminished blood supply. |
 | | The reduced blood flow to the bone may be the result of blockage by a blood clot, medication, or the deliberate stoppage of flow during surgery or because of measures taken to control a hemorrhage (major bleed). |
 | | Avascular necrosis of the bone is a complication of corticosteroid use, trauma, systemic lupus erythematosus, pancreatitis, alcoholism, gout, and sickle cell disease, as well as other diseases. |
