![]() The size of the fragment and the region of the posterior wall involved.With posterior wall fractures, one should always evaluate the CT scan for: In this example, the posterior column is seen to be intact as is the anterior rim.The displaced posterior wall fragment(s) is superimposed on the ilium and thus difficult to see. ![]() The iliac oblique radiograph demonstrates the integrity of the posterior column, the iliac wing, and the anterior border of the bone. Certainly, the CT scan will be inspected for incarcerated fragments but the reduction is appropriate at this stage. The femoral head is reduced and comparison to the other side would demonstrate near congruence of the reduction. The anterior column is intact, as is the obturator foramen. It appears as a large fragment however, there may be a perforation of the cortex based on this image. It extends cranially above the acetabulum. ![]() In this example, a large piece involving a small portion of the radiological roof is seen.If the hip has been reduced, the congruence of the reduction should be inspected on this view, and the involvement (or lack thereof) of the acetabular roof should be considered. The integrity of the anterior column and the obturator foramen is evaluated on this view. ![]() The obturator oblique radiograph is the best source of information of the size, character, and displacement of the posterior wall fragment because the femoral head and ilium are rotated to allow exposure of the retro- and supraacetabular surfaces. ![]()
