On a Judet oblique radiograph (obturator oblique view), which structure is best visualized for assessing an anterior column acetabular fracture?

• A Posterior column and anterior wall
• B Sacral ala
• C Quadrilateral surface
• D Anterior column and posterior wall ✓

Explanation

The obturator oblique view (Judet view with the affected side rotated 45 degrees toward the film) best visualizes the anterior column and posterior wall. The iliac oblique view (opposite rotation) best visualizes the posterior column and anterior wall. These two oblique views, along with the AP pelvis, are essential for classifying acetabular fractures according to the Judet-Letournel system.
