Pelvic Girdle
1st year 1st quarter
*AP affected hip
**If this is the initial exam of the hip you might need to take a AP pelvis instead of a AP hip
*Lateral affected hip
HIP
Structures shownAP Hip
• Head, neck, trochanters and proximal one third of the body of the femur. *The pubic symphysis must be shown on one view of the hip
Good Film
• Lower portion of the ilium and pubic symphysis should be included on the film.
• Any orthopedic appliance should be included in its entirety
• The greater trochanter should be in profile• The long axis of the femoral neck should be seen• The proximal third of the femur should be
included• Little or none of the lesser trochanter should be
visible beyond the medial edge of the femur

OUCH!
Structures shownLateral hip(mediolateral Lauenstein method)
• A lateral projection of the hip is demonstrated, showing the acetabulum, the proximal end of the femur, and the relationship of the femoral head to the acetabulum
Good Film
• ***Don’t do this view if fracture is likely or patient is post-op for less than three days.
• The hip joint should be centered to the film.
• The hip joint, acetabulum, and femoral head should be well demonstrated.

Pediatric Patients: Congenital Hip Abnormalities
• AP pelvis
• Modified Cleaves (***not done if fracture is suspected)
Diaper
“Frog legs”
ModifiedCleaves method
For pediatric patients with congenital hip abnormalities
Structures shownAxiolateral Hip (Danelius-Miller)
• Axiolateral projection of the acetabulum and the proximal femur to include the head, neck, and trochanters. *** This view is done to see the neck
Good Film:
• Do this view if fracture is likely or patient is post-op.• As much of the femoral neck should be seen as possible
without overlap from the greater trochanter• Only a small amount of the lesser trochanter should be
seen on the posterior surface of the femur• A small amount of the greater trochanter should be seen on
the anterior and the posterior surfaces of the proximal femur (when it is safe for the femur to be inverted)
• The soft tissue shadow of the unaffected thigh should not overlap the hip joint or proximal femur.
• The hip joint with the acetabulum should be included .

Judet’s method
• RPO
• LPO
Structures shown: The acetabular rim
• We want AP oblique position to include both hips on each film.(always do both obliques) The whole pelvis should be included. The iliac wing is also well visualized.
Different than Merrill’s:
Why would you do them?
• Used to demonstrate fractures of the posterior (ilioischial) column and anterior rim of the acetabulum.
