title: [The aetiology of avascular necrosis following a treatment of congenital hip dislocation and its relationship to a classical Legg-Calvé-Perthes' disease].
abstract: The process of creation of avascular necrosis will be explained on account of compression of the lateral retinacular arteries in Lorenz-position, during the treatment of congenital hip dislocation and variable development of medial and lateral arteries supplying the proximal epiphysis of femur. Also will be discussed the connection between the classical Legg-Calvé-Perthes' disease and the so-called hip-dislocation-Perthes' disease.
