Avascular Necrosis

Avascular necrosis (AVN) is also known as osteonecrosis. It is a condition that occurs when the blood supply to bone tissue is cut off. When bone cells and bone marrow cells are starved of their blood supply, they can die. This can lead to mechanical failure (collapse) of the bone.

Any bone tissue can be affected by Avascular Necrosis, but it is most common in the hips. The condition can occur on one side of the body or on both sides.

Avascular Necrosis can be trouble when it occurs near a joint. The bone surrounding the joint can collapse. This can then result in abnormal wear of the joint and premature failure.

Avascular necrosis is a potentially disabling condition. The outcome depends on the location and degree of bone and joint damage.

Excessive alcohol use and prolonged high-dose steroid use are the two greatest atraumatic risk factors for Avascular Necrosis.
