Avascular necrosis is the death of bone tissue due to a lack of blood supply. A broken bone or dislocated joint can interrupt the blood flow to a section of bone…. AVN is the loss of blood supply to the bone. Once the blood supply diminishes and the bone begins to starve, it sends a signal to the brain that something is wrong. This signal is interpreted as pain by the brain. It is constant because the bone is continually starving from the lack of blood supply.
