What is  avascular necrosis ?

Avascular necrosis: Bone is a living tissue that is constantly turning over; this involves tightly regulated systems of bone addition and subtraction. In order to deliver the cells that are responsible there needs to be adequate blood flow. If the blood flow is disrupted significantly, the affected areas can undergo avascular necrosis (avn).

Once collapse occurs, some sort of resurfacing/replacement required to manage pain. ...Read more
