Badgley³⁹⁰ reviews the theories of the cause of congenital dislocation of the hip and discusses the syndrome of arthrogryposis multiplex congenita. He concludes that the essential feature for his thesis is the evidence of a primary anterior displacement of the head associated with external rotation of the femur. Failure of normal rotation of the limb bud during embryologic life results in anteversion of the head and neck of the femur. Anteversion of the head produces the flat socket. The neck of the femur lies against the posterior rim of the socket, with the greater trochanter posteriorly. Hypoplasia of the posterior rim results from this faulty pressure. The flat socket does not maintain the head in position. A gradual posterior displacement of the head and neck occurs as a result of the greater posterior angle of the os innominatum and the pull of the gluteal muscles.
