title: [Etiology and pathogenesis of aseptic necrosis of the femur head in children].
abstract: The authors have investigated the blood supply of the hip joint in aseptic necrosis following a bloodless reduction of a congenital dislocation of the hip with the help of serial angiography in 6 patients aged 3.5 to 8 years. The angiographic examination has allowed us to determine a reduction in the vascular field on the side affected by hip joint dysplasia as compared with the values on the conventionally normal side. The experimental investigation of the vessels by means of introduction of a radiopaque mixture has demonstrated that in case of a non-physiological position of the lower extremities (Lorenz I) a compression of the blood supplying vessels of the hip joints takes place.
