Question

Which of the following projections might be used to examine an acute injury to the shoulder?

1. PA oblique projection (Scapular Y)
2. Transthoracic lateral projection
3. AP projection with external rotation
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
d. 1, 2, and 3

Answer 1

To examine an acute shoulder injury, PA oblique projection (Scapular Y), Transthoracic lateral projection, and AP projection with external rotation are utilized. The correct answer for which projections might be used to examine a shoulder injury is d. 1, 2, and 3.

Step-by-step explanation:

To examine an acute injury to the shoulder, the following projections might be used:

• PA oblique projection (Scapular Y)
• Transthoracic lateral projection
• AP projection with external rotation

Each of these imaging techniques can provide valuable information about the shoulder's anatomy and potential injuries. The Scapular Y and AP projections can help visualize the alignment of the humerus with the scapula and reveal any dislocations or fractures. The Transthoracic lateral projection is particularly useful for seeing through the shoulder joint in a side view, which can help identify specific types of fractures or dislocations when the shoulder is not clearly seen in other views due to pain or swelling.

Therefore, the correct answer for which projections might be used to examine a shoulder injury is d. 1, 2, and 3.
