FIG. 55.3 Transverse/Flexion Hip View. (A) Linear array transducer is in the axial plane posterolaterally over the hip joint with the hip lexed.
(B) Scan area (dotted lines) on a prone computed tomography (CT) scan. Scan demonstrates relationship of femoral head (H), metaphysis (m), and
ischium (i) in the normal hip on the left and the dislocated hip on the right. (C) Normal hip sonogram shows echolucent femoral head (H) surrounded
by metaphysis (m) (anterior) and ischium (i) (posterior), forming a U around the femoral head. L, Lateral; P, posterior. (D) Dislocated hip sonogram
shows sonolucent femoral head (H) displaced posterolaterally. The U coniguration of normal metaphysis (m) and ischium (i) is not seen. See also
