This document describes several standard radiologic imaging projections for evaluating the hip. It outlines the patient positioning and beam direction for anterior-posterior (AP), cross-table lateral, frog leg lateral, Clements-Nakayama, and Dunn views. It also discusses AP pelvic and 45-degree Judet oblique views for assessing the acetabulum. The frog leg lateral view is not recommended for patients suspected of hip fracture or dislocation.

1. Hip radiologic imaging
standard projection
• AP view:
- patient is supine with
the foot internally
rotated 15 deg to obtain
best views of the
femoral neck;
- central beam is directed
toward the femoral
head

2. • Lateral View (cross table
lateral view)
- surgical lateral view:
- this view should be obtained on all
patients suspected of having a hip
fracture or dislocation;
• - patient is supine; the opposite
hip is flexed and abducted;
• - cassette is placed against
the lateral aspect of the affected
hip
• - central beam is directed
horizontally toward the groin with
about 20 degree of cephalic tilt;

3. • Frog leg view:
• - do not order a frog
leg lateral in any patient
suspected of having hip
fracture or dislocation
 patient is supine w/ knees
flexed, soles of feet
together, and the thighs
maximally abducted;
- central beam is directed
vertically or with a 10 to 15
deg cephalic tilt to a point
slightly above pubic
symphysis;

4. • Clements-Nakayama view 4
• lateral projection
demonstrating the neck of
the femur without
movement of the either
limb
• the ideal projection for
bilateral hip or femur
trauma

5. • Dunn view
• lataral projection to aid
and diagnose
femoroacetabular
impingement (FAI) due
to its increased
sensitivity for detecting
femoral head-neck
asphericity.

6. Acetabular evaluation
• AP pelvic view

7. Acetabular evaluation
• 45-degree oblique
views of the pelvis
commonly called Judet
views-
– Iliac oblique view
– Obturator oblique view
