Answer

The frequency of AVN depends on the site involved. The most common site is the hip; other locations include the carpals, talus, femur, metatarsal, mandible, and humerus. In the United States, approximately 15,000 new cases of AVN are reported each year. AVN accounts for more than 10% of total hip replacement surgeries performed in the United States. Osteonecrosis of the jaw associated with bisphosphonate has also been well studied and reported. Most patients with osteonecrosis of the jaw also had an ongoing malignancy and/or had undergone a recent dental procedure. [9, 4, 10]
