Routine Shoulder Review

Question 1

The –1– position will demonstrate the greater tubercle on the –2– surface of the humerus.

Answer 1

External rotation; lateral

Question 2

To adequately demonstrate the shoulder in a “true” AP, the patient should…?

Answer 2

Be rotated slightly toward the side being examined

Question 3

The SR is directed –1– for an AP projection of the shoulder.

Answer 3

1 inch inferior to coracoid

Question 4

The lesser tubercle will be visualized on the –1– surface with –2– rotation of the arm for an AP shoulder radiograph.

Answer 4

Medial; Internal

Question 5

The inferosuperio axial projection of the glenohumeral joint is known as the –1– Method.

Answer 5

 Lawrence

Question 6

The arm is abducted –1– degrees if possible for the inferosuperior axial projection of the glenohumeral joint.

Answer 6

90

Question 7

The hand is –1– for the AP humerus.

Answer 7

Supinated

Question 8

The transthoracic lateral shoulder requires that the –1– arm be positioned

Answer 8

Affected: down at the patient’s side

Question 9

For the above question, the unaffected arm is termed the –1– arm.

Answer 9

Remote

Question 10

If the patient is unable to adequately separate their shoulders for the transthoracic lateral projection, the CR should be adjusted –1–.

Answer 10

10-15 degrees cephalic

Question 11

Give 2 possible respiration instructions for the transthoracic lateral projection of the shoulder:

Answer 11

1. Deep Inspiration

2. Slow breathing with long exposure

Question 12

1. Deep Inspiration-

2. Slow breathing with long exposure

Answer 12

1. Blacks out lungs and increases contrast in the proximal humerus.
2. Expose 3-4 secs while patient is breathing and use motion to blur out the ribs and surrounding structures

Question 13

The routine for a humerus is to have the patient rotate their hand and arm for 2 separate radiographs. If the hand is internally rotate, this is considered a –1– of the humerus.

Answer 13

Lateral Position

Question 14

For a routine humerus there is one position that has the hand and arm externally rotated. This position is the…

Answer 14

AP

Question 15

The CR should be directed to the –1– for a PA hand radiograph.

Answer 15

Third MCPJ

Question 16

List the 3 criteria needed for a decubitus radiograph.

Answer 16

1. Vertical IR
2. Recumbent pt
3. Horizontal CR

Question 17

The shoulder joint is formed by the articulation of the –1– and the –2–.

Answer 17

Humeral head; Glenoid Fossa

Question 18

The scapular Y position is beneficial for dislocations. State the structures that make the Y appearance on the radiograph:

Answer 18

1. Acromion Process
2. Coracoid Process
3. Scapular Body

Question 19

State how a scapular Y informs us of an anterior versus posterior dislocation:

Answer 19

Anterior- The humerus head will be located underneath the coracoid process.
Posterior- The humerus head will be located underneath the acromion process.

Question 20

If a patient is able to sit or stand up for a scapular Y radiograph, what oblique would be beneficial/preferred if the left shoulder was the injured one?

Answer 20

LAO

Question 21

What if the pt was not able to sit up and had to have the scapular Y done recumbent? Then what position would be beneficial for the left shoulder?

Answer 21

RPO

Question 22

How many degrees do we need to oblique the pt for a scapular Y radiograph?

Answer 22

45-60

Question 23

When performing an axial shoulder position with a seated pt, what projection is being utilized?

Answer 23

Superoinferior

Question 24

The CR may be directed –1– degrees –2– when performing the position/projection in number 22 (Superoinferior)

Answer 24

1. 5-15 degrees

2. Toward the Elbow

Question 25

When positioning a scapular on a prone pt, the shoulder –1– the IR is best demonstrated.

Answer 25

Closest

Question 26

When an LAO or RAO scapular “Y” exam is performed the CR may be directed to the –1– border of the scapula for easy centering.

Answer 26

Medial

Question 27

When performing an axial Lawrence Method the CR will be….

Answer 27

Horizontal

Question 28

What position should be done on the pt who is ordered for a routine AP shoulder series and they can’t rotate their arm at all?

Answer 28

Lawrence Method

Transthoracic

Question 29

List 2 reasons to perform a chest exam in the upright position.

Answer 29

1. Prevent engorgement of pulmonary vessels

2. Get diaphragm at its lowest point

Question 30

Name the most lateral carpal bone of the distal row.

Answer 30

Hamate/Unciform
