In brief: 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). Avn can lead to collapse of the area and arthritis if it occurs near joints.
