Q

Situation: A portable AP and lateral hip study is ordered for a patient who is in recovery following hip replacement surgery. The radiograph of the AP hip reveals that the upper portion of the acetabular prosthesis is slightly cut off but is included on the lateral projection. Should the technologist repeat the AP projection? Why or why not?

A

Yes. Any orthopedic appliance or prosthesis must be seen in its entirety in both projections.

46
Q

Denellius miller / crosstable hip

A

opposite leg up

top of film by crest, winged out to 60 degrees

47
Q

Situation: A unilateral frog-leg (modified Cleaves) demonstrates foreshortening of the femoral necks. The physician is unsure if ther is a defect withing the anatomical neck. What can be done to minimize destortion of the neck during a repeat expsoure?

A

Only abduct the femurs 20º to 30º from the veritcal rather than 45º to minimize distortion of the femoral neck.

48
Q

Situation: A radiograph of an axiolateral (inferosuperior) projection of a hip demonstrates a soft tissue density that is visible across the affected hip and acetabulum. This artifact is obscuring the image of the proximal femur. What is the most likely cause of the artifact, and how can it be prevented from showing up on the repeat exposure?

A

It is soft tissue from the unaffected thigh. This leg must be flexed and elevated high enough to keep it from superimposing the affected hip.

49
Q

Situation: An initial AP pelvis radiograph reveals possible fractures involving the lower anterior pelvis. The emergency room physician asks for another projection to better demonstrate this area of the pelvis. The patient is traumatized and must remain in a supine position.
