Routine Shoulder Review Flashcards
The –1– position will demonstrate the greater tubercle on the –2– surface of the humerus.
External rotation; lateral
To adequately demonstrate the shoulder in a “true” AP, the patient should…?
Be rotated slightly toward the side being examined
The SR is directed –1– for an AP projection of the shoulder.
1 inch inferior to coracoid
The lesser tubercle will be visualized on the –1– surface with –2– rotation of the arm for an AP shoulder radiograph.
Medial; Internal
The inferosuperio axial projection of the glenohumeral joint is known as the –1– Method.
Lawrence
The arm is abducted –1– degrees if possible for the inferosuperior axial projection of the glenohumeral joint.
90
The hand is –1– for the AP humerus.
Supinated
The transthoracic lateral shoulder requires that the –1– arm be positioned
Affected: down at the patient’s side
For the above question, the unaffected arm is termed the –1– arm.
Remote
If the patient is unable to adequately separate their shoulders for the transthoracic lateral projection, the CR should be adjusted –1–.
10-15 degrees cephalic
Give 2 possible respiration instructions for the transthoracic lateral projection of the shoulder:
- Deep Inspiration
2. Slow breathing with long exposure
- Deep Inspiration-
2. Slow breathing with long exposure
- Blacks out lungs and increases contrast in the proximal humerus.
- Expose 3-4 secs while patient is breathing and use motion to blur out the ribs and surrounding structures
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.
Lateral Position
For a routine humerus there is one position that has the hand and arm externally rotated. This position is the…
AP
The CR should be directed to the –1– for a PA hand radiograph.
Third MCPJ
List the 3 criteria needed for a decubitus radiograph.
- Vertical IR
- Recumbent pt
- Horizontal CR
The shoulder joint is formed by the articulation of the –1– and the –2–.
Humeral head; Glenoid Fossa
The scapular Y position is beneficial for dislocations. State the structures that make the Y appearance on the radiograph:
- Acromion Process
- Coracoid Process
- Scapular Body
State how a scapular Y informs us of an anterior versus posterior dislocation:
Anterior- The humerus head will be located underneath the coracoid process.
Posterior- The humerus head will be located underneath the acromion process.
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?
LAO
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?
RPO
How many degrees do we need to oblique the pt for a scapular Y radiograph?
45-60
When performing an axial shoulder position with a seated pt, what projection is being utilized?
Superoinferior
The CR may be directed –1– degrees –2– when performing the position/projection in number 22 (Superoinferior)
- 5-15 degrees
2. Toward the Elbow
