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.
For healthy people, the risk of AVN is small. Most cases are the result of an underlying health problem or injury. Possible causes include: Dislocation or fracture of the thigh bone (femur). This type of injury can affect the blood supply to the bone, leading to trauma-related avascular necrosis.
