Acetabulum: Judet obliques
Two 45° posterior obliques: affected side up shows the anterior column; affected side down shows the posterior column.
Why Judet
The acetabulum is a cup made by two columns of bone that form an upside-down Y. The anterior column, the iliopubic column, runs from the iliac crest down to the pubis. The posterior column, the ilioischial column, runs down to the ischium. On an AP pelvis these overlap, so after a pelvic or hip injury two Judet views, 45 degree posterior obliques, are taken to see each column and each rim of the acetabulum. Many trauma centers now go to CT, but the Judet views are still taken and are on the 2027 ARRT projection list.
