Avascular necrosis (AVN) is a disease that may affect several different bones as a result of temporary or. permanent loss of the blood supply to these bones. The femoral head is most commonly affected by this. disease. Usually, the patients are in their third, fourth or fifth decade of life at the time of diagnose. Initially, patients are asymptomatic, but, in time, AVN leads to joint destruction, requiring surgical. treatment and, in latter stages, total hip replacement.
