title: [Osteonecrosis of the femur head caused by sickle cell anemia in Benin. Epidemiologic and radiologic aspects].
abstract: The author reports 19 aseptic necrosis of the femoral head, due to sickle cell anemia, collected in 14 black people native from Benin. Sickle cell anemia is the most frequent etiology of osteonecrosis there. They are generally observed between 10 and 30 years of age. A systematic and complete study of the radiological signs has been carried out. The peculiar severity of the disease in black Africa is related to the chronicity of the sickling disorder, the delay brought to the diagnostic, the lack in therapeutic media.
