While defining THD, one of the basic criteria is the position of the displaced femoral head with respect to the inhabited acetabulum, i.e., a topographical criterium, and this is identical for adults and children. Allis’ classification will be used here. A line drawn from the anterosuperior spine of the ilium through the center of the acetabulum to the ischial tuberosity divides dislocations of the hip into two main groups (Fig. 3.1): when the femoral head is displaced posteriorly to this line, it is designated posterior; when the head is in front of this line, it is called anterior.
