Clavicle Positioning Quiz

Evaluation criteria for AP clavicle

• entire clavicle centered on the image

• Lateral half of the clavicle above the scapula, with the medial half superimposed the thorax

Evaluation criteria for the AP axial clavicle

• entire clavicle along with AC and SC joints

• Lateral two thirds of the clavicle projected above the ribs and scapula with the medial end superimposing the thorax

• Clavicle in a more horizontal orientation, as compared with the AP projection

What are all the views for the clavicle?

• AP

• AP axial

• PA

• PA axial

If your patient is supine, what is the degree of angulation for the AP axial?

15 to 30 degrees cephalad

If your patient is standing upright, what is the degree of angulation for the AP axial?

15 to 30 degrees

If the patient is in a lordotic position, what is the degree of angulation for the AP axial?

0 to 15 degrees

Respiration for the AP axial

Suspend at the end of full inspiration

Respiration for the AP

Suspend at the end of exhalation

Central ray consideration for the AP axial regarding thickness of the thorax and how that will affect the degree of angulation

Cephalic CR angulation can vary depending on the thickness of the chest; thinner patients require increased angulation to project the clavicle above the scapula and ribs

What is the following projection?

AP clavicle

What is the following projection?

AP axial
