Avascular Necrosis Information

Although avascular necrosis can occur in any bone, the condition tends to affect the ends of long bones, such as the femur (the bone extending from the knee joint to the hip joint).

This condition does not always cause symptoms in the early stages, but as it progresses, symptoms may include:
 
What causes avascular necrosis? There are several possible causes; they can be separated as those related to trauma and those not related to trauma. The two most common nontraumatic causes are steroid medicines and alcohol use.
