Forage Biopsy plus Autologous Bone Grafting: Indications and Limits
Avascular necrosis (AVN) of the femoral head is the end point of a variety of disease processes, resulting in decreased blood flow and eventual destruction of the hip joint . It affects mostly young patients in the 3rd, 4th, and 5th decades of life. Between 10,000 and 20,000 new cases of AVN of the femoral head are diagnosed each year in the United States. The average age of all patients undergoing total hip arthroplasty (THA) is 66 years, whereas the average age for patients with AVN undergoing THA is 40 years . Due to the relatively young age of onset, these patients are often subjected to multiple surgical procedures during their lifetime, and because their disability occurs during their prime working years, social costs to the community are high. For these reasons, the economic impact of AVN is much greater than the absolute numbers suggest.
