What to look for in normal pelvis radiograph
- Trace the pelvic brim (iliopectineal line) from the sacrum round to the symphysis on each side.
- Trace the sacral arcuate lines and compare the sacroiliac joints and symphysis side to side.
- Check both hips, including Shenton's line; unfused apophyses in young people are normal variants.
