Posterior hip dislocation with slice fracture of the femoral head: removal of the cephalic fragment.

Three patients with posterior dislocation of the hip associated with Pipkin type II fracture of the femoral head were treated surgically by removal of the cephalic fragment, as closed reduction had not been satisfactory. The clinical and radiographic results were good after 1 year, and none of the patients showed radiographic signs of avascular necrosis.
