In the radiographic evaluation of an acetabular fracture, the obturator oblique (Judet) view is obtained by rotating the patient 45 degrees toward the injured side. Which structures are best demonstrated on this view?
- A Posterior wall and anterior column ✓
- B Anterior wall and posterior column
- C Ilioischial line and iliopectineal line together
- D Sacral foramina and SI joint
Correct answer: A. Posterior wall and anterior column
Explanation
On the obturator oblique view the pelvis is rotated 45 degrees toward the affected side, which profiles the obturator foramen and shows the posterior wall and the anterior column to best advantage. The iliac oblique view, obtained by rotating away from the injured side, demonstrates the anterior wall and the posterior column along with the greater sciatic notch. The iliopectineal and ilioischial lines are assessed on the AP pelvis view.
