United States
According to the American Academy of Orthopaedic Surgeons, 10,000 to 20,000 people in the United States alone develop Avascular Necrosis (or Osteonecrosis) each year, and most of them are between 20 and 50 years of age.[1] Also notable, AVN accounts for more than 10% of total hip replacement surgeries performed in the United States.[2]

Japan
A Japanese survey estimated 2500-3300 cases of AVN of the hip occur in Japan each year. This Japanese study estimates 34.7% of the national AVN cares were due to corticosteroid use, 21.8% to alcohol abuse, and 37.1% to idiopathic mechanisms.[3]
