X-RAY THE HUMERUS

X-Ray Images the Humerus


You have a formal request for a radiologic examination of the humerus. 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 the patient's jewelry is removed as necessary.

(2)  Ensure the patient has removed all clothing under the area of study as necessary.

NOTE: Gown the patient as necessary.

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 1/2 of a 14" X 17" cassette for the both views.

7.  Place the cassette on the table lengthwise.

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 portion of the film being used.

d.  Adjust the conefield to full field coverage.

9.  Position the humerus.

a.  AP view.

(1)  Place the patient supine with the coronal plane rotated 10 to 15 degrees toward the affected side.

(2)  Center the humerus to the appropriate half of the cassette.

(3)  Position the epicondyles parallel to the cassette.

(4)  Center the acromion process and epicondyles equidistant from the respective film borders.

b.  Lateral view.

(1)  Place the patient supine with the coronal plane rotated 10 to 15 degrees towards the affected side.

(2)  Center the humerus to the appropriate half of the cassette.

(3)  Flex the elbow and rotate the humerus 90 degrees.

(4)  Position the epicondyles perpendicular to the cassette.

(5)  Turn the hand towards the body with the posterior surface in firm contact with the hip.

(6)  Center the acromion process and epicondyles equidistant from the respective film borders.

NOTE: The forearm should extend off the lateral edge of the cassette with the shaft of the humerus parallel to the lateral border of the cassette.

10.  Immobilize the body part by placing a sandbag on or against the hand.

11.  Place the appropriate identification marker on the cassette.

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

13.  Tell the patient, "STOP BREATHING AND DO NOT MOVE."

14.  Make the exposure.

15.  Tell the patient, "RELAX AND BREATHE NORMALLY," and remove immobilization.

16.  Process the film.
