Avascular Necrosis

Also Know As Osteonecrosis

Avascular Necrosis

Avascular necrosis (otherwise known as osteonecrosis) is the death of a bone segment due to inadequate blood supply. In the absence of blood, the bone’s tissue dies, leading to its collapse. This can occur either due to an injury or spontaneously. In the latter case, it is often the result of a blockage in the artery which feeds the area.

The condition is characterised by pain in the affected joint, and a subsequently limited range of its motion. The incidence of avascular necrosis has been linked to smoking, and excessive consumption of alcohol and drugs.
