Fig. 6A–D.

(A) A computed tomography scan shows a normally positioned hip after closed reduction with contrast surrounding the femoral head. (B) Arthrographic contrast surrounding the femoral head after successful closed reduction of the hip is demonstrated. Note the smooth arc (line) formed by the femoral metaphysis and the pubic bone anteriorly. (C) A dislocated hip is shown. Note discontinuity of the normal arc (discontinuous line) formed by the femoral metaphysis and pubic bone. Air is seen in the soft tissues from the procedure. (D) This is a mildly posteriorly displaced hip after closed reduction. F = femur; I = ischium; P = pubis.
