What is X-RAY PELVIS BOTH HIPS AP?

The AP pelvis view is part of a pelvic series examining the iliac crest, sacrum, proximal femur, pubis, ischium, and the great pelvic ring.

Indications

This view is of considerable importance in the management of severely injured patients presenting to emergency departments 1. It helps to assess joint dislocations and fractures (i.e. iliopectineal line, ilioischial line, Shenton line) in the trauma setting, as well as, bone lesions and degenerative diseases.

Patient position

• Patient is supine


• Lower limbs are internally rotated 15-25° from the hip (do not attempt this if a fracture is suspected) to demonstrate an AP view of the proximal femur

Technical factors

• AP projection


• Centering point
  
  
  • The midpoint of the anterior superior iliac spine and the pubic symphysis


• Collimation
  • 
    Laterally to the skin margins

  • Inferior to the proximal third of the femur
