X-Ray Images the Hip

You have a formal request for a radiologic examination of the hip. You have the assistance of additional personnel if required. You will need a properly equipped X-ray exposure room with various sizes of film in cassettes, sandbags, lead apron, letter markers, calipers, and various sponges.

1.  Select the required view(s) based on the request.

2.  Gather the necessary materials and supplies.

a.  Appropriate cassettes.

b.  Radiographic film.

c.  Sandbags.

d.  Letter markers.

e.  Tape.

f.  Positioning sponges.

g.  Lead shielding.

h.  Calipers.

3.  Prepare the patient.

a.  Bring the patient into the X-ray room.

b.  Ensure the patient is properly dressed.

(1)  Ensure foreign objects are removed from patient as necessary.

(2)  Ensure the patient's clothing is removed as required.

(3)  Use a drape sheet or patient gown to cover the patient as needed.

c.  Explain the procedure if applicable.

d.  Assist the patient onto the X-ray table.

4.  Measure the body part through the entry-exit site of the central ray.

5.  Set the control panel.

a.  Consult the technique chart.

b.  Set the appropriate mAs and kVp on the control panel.

6.  Select the proper size cassette.

NOTE: Use a 10" X 12" cassette for the AP view and a 14" X 17" cassette for the frog leg view.

7.  Place the cassette in the bucky according to the required view.

a.  Lengthwise for the AP view.

b.  Crosswise for the frog leg view.

8.  Position the overhead tube.

a.  Set the tube angle perpendicular to the film.

b.  Set the source to image receptor distance (SID) to 40 inches (101 cm).

c.  Center the tube to the cassette.

d.  Adjust the conefield to full field coverage.

9.  Position the hip.

a.  AP view.

(1)  Place the patient supine with the midsagittal plane perpendicular to the table.

(2)  Extend the lower extremities.

(3)  Rotate both feet and legs medially to form a 15 degree angle.

NOTE: This will ensure the head and neck of each femur are parallel to the film.

(4)  Place the sagittal plane 2" medial to the ASIS and the transverse plane through the greater trochanter to the center of cassette.

b.  Frog leg view.

(1)  Place the patient supine with the midsagittal plane perpendicular to and over the centerline of the table.

(2)  Flex both knees.

(3)  Place the soles of both feet together and over the centerline of the table.

(4)  Abduct each thigh to form a 40 degree angle from the vertical position.

NOTE: This will create and angle of approximately 80 degrees.

(5)  Place the iliac crests 2" below the upper edge of the cassette.

10.  Immobilize the body part as necessary.

11.  Place the appropriate letter marker on the cassette.

12.  Place the lead apron across the patient's lap.

13.  Tell the patient, "DO NOT MOVE."

14.  Make the exposure.

15.  Tell the patient, "RELAX," and remove immobilization.

16.  Process the film with the patient's identification.
