Osteonecrosis of the Femoral Head [PDF]
Journal of the American Academy of Orthopaedic Surgeons, 1999 New cases of osteonecrosis of the femoral head in the United States number between 10,000 and 20,000 per year. This disease usually affects patients in their late 30s and early 40s. Although a number of authors have related specific risk factors to this disease, its etiology, pathogenesis, and treatment remain a source of considerable controversy. This
