Shoulder & Clavicle (Questions 1-20)
Q1. What is the common term for idiopathic chronic adhesive capsulitis?
Correct Answer: Frozen Shoulder
Adhesive capsulitis is the medical term for frozen shoulder, a condition
characterized by stiffness and pain in the shoulder joint .
Q2. Which AP shoulder projection demonstrates the lesser tubercle in profile
medially?
Correct Answer: Internal Rotation
In internal rotation, the humeral epicondyles are perpendicular to the image
receptor (IR), placing the lesser tubercle in profile on the medial side .
Q3. For AC joint weight-bearing studies, patients should NOT be asked to hold
the weights with their hands. TRUE or FALSE?
Correct Answer: True
Weights should be attached to the wrists rather than held in the hands to
maintain consistent positioning and prevent muscle contraction artifacts .
Q4. A posterior dislocation of the shoulder occurs more frequently than an
anterior dislocation. TRUE or FALSE?
Correct Answer: False
, Anterior dislocations are significantly more common (over 95% of shoulder
dislocations) than posterior dislocations .
Q5. Sonography is an effective diagnostic tool in studying the shoulder joint.
TRUE or FALSE?
Correct Answer: True
Ultrasound is effective for evaluating rotator cuff tendons, bursae, and other soft
tissue structures of the shoulder .
Q6. A radiograph of an AP axial projection of the clavicle demonstrates the
clavicle within the mid-aspect of the lung apices. How should the technologist
correct this error?
Correct Answer: Increase the cephalic CR angle during repeat exposure
Increasing the cephalic angle projects the clavicle higher, away from the lung
apices for better visualization .
Q7. The AP humerus requires that the humeral epicondyles are ________ to the
IR.
Correct Answer: parallel
The epicondyles must be parallel to the IR for a true AP projection without
rotation .
Q8. A patient enters with multiple injuries including a possible fracture of the
left proximal humerus. Which positioning rotation should be performed?
Correct Answer: AP and horizontal beam transthoracic lateral shoulder
projection
This trauma projection allows visualization of the proximal humerus without
moving the injured arm .
