The hip is a ball and socket joint. The ball is the femoral head and the socket is the acetabulum.
At birth, the femoral head and the acetabulum are made of mostly cartilage and are relatively soft. For the joint to form properly, the femoral head and acetabulum must be orientated correctly.
DDH is a progressive condition in which this does not happen. The term encompasses many abnormalities, from mild under-development of new born hips to the stiff unreducible hip.
Imaging U/S up to 4-6mths until femoral heads ossify

The Hilgenreiner Line is a horizontal line drawn through the top of the triradiate cartilage.
Perkins Line is a vertical line through the most lateral ossified margin of the roof of the acetabulum perpendicular to Hilgenreiners Line.The ossification centre of the femoral head should be located in the medial lower quadrant of the line intersection.
