Pelvis and hip film check
Legs turned in 15 to 20° so the femoral necks lengthen and the lesser trochanters almost disappear, unless a fracture is possible. Then nothing gets rotated.
The AP pelvis
On the AP pelvis, turn both legs in 15 to 20 degrees. That puts the femoral necks parallel to the IR so they show at full length, and it hides the lesser trochanters behind the femoral shafts, or leaves only a small edge showing. Center midway between the ASIS and the symphysis pubis. The iliac wings and obturator foramina should look the same on both sides. If one obturator foramen looks narrower, the pelvis was rotated. Large lesser trochanters and short femoral necks mean the legs were turned out.
