A resident is reviewing a series of Judet views of an acetabular fracture. On the obturator oblique radiograph (affected hemipelvis elevated 45 degrees), which structures are best profiled?
- A Posterior column and anterior wall
- B Ilioischial line and greater sciatic notch
- C Anterior column and posterior wall ✓
- D Posterior wall and quadrilateral plate
Correct answer: C. Anterior column and posterior wall
Explanation
The obturator oblique view profiles the anterior column, the posterior wall, and the entire obturator ring. The iliac oblique view, obtained by elevating the uninjured side, instead shows the posterior column, the anterior wall, and the greater sciatic notch. Confusing these two views is the classic error; remembering that the named bone shown en face matches its own column solves it.
