For this view, the patient is placed in a supine position with legs together, hips and knees extended, and the feet inverted (turned inwards) 15 degrees. The foot inversion brings the anteverted femoral neck into a plane perpendicular to the radiograph. If properly positioned, the lesser trochanter should be posterior (its tip may project slightly across the medial border of the femur).

Identify the following:

1. femoral head

2. margin of acetabulum

3. hip joint space

4. fovea (capitis)

5. greater trochanter

6. lesser trochanter

7. intertrochanteric crest and line
