Avascular Necrosis. In adolescents and young adults with avascular necrosis (AVN), the blood supply to the hip joint is interrupted and the bone begins to die. Learn more about Avascular Necrosis.
Avascular necrosis, also called aseptic necrosis, ischemic bone necrosis, or osteonecrosis, death of bone tissue caused by a lack of blood supply to the affected area. Avascular necrosis most commonly affects the epiphyses (ends) of the femur (thigh bone); other commonly affected bones include those of the upper arm, the shoulder, the knee, and the ankle. Avascular necrosis tends to occur in men more often than women and typically is diagnosed between ages 30 and 50.
