Question 1

A patient fell off her bike onto her shoulder and subsequently went to emergency department. Initial radiographs were negative for fracture, and she was referred to physical therapy with shoulder pain. On evaluation you suspect an acromioclavicular strain. What radiographic projection would help confirm this diagnosis?

A) Anteroposterior of the shoulder
B) Lateral view of the scapula
C) Acromioclavicular bilateral view with and without weights
D) Axillary view of glenohumeral joint

Acromioclavicular bilateral view with and without weights

Accepted Answer

C) Acromioclavicular bilateral view with and without weights is the specific radiographic projection used to evaluate the acromioclavicular joint for strains, separations, or other pathologies by comparing the affected side to the unaffected side under stress (with weights) and without stress.

Question 2

&#10;&#10;-Refer to the figure. Name the radiographic projection.&#10;A) Anteroposterior external rotation&#10;B) Lateral view of the scapula&#10;C) Anteroposterior internal rotation&#10;D) Axillary view of glenohumeral joint

Accepted Answer

The anteroposterior internal rotation projection is characterized by the humeral head appearing in profile and the lesser tubercle being visible medially, which is typical for this type of radiographic view.

Question 3

&#10;&#10;-Refer to the figure. You have chosen the correct answer because you recognized what region of anatomy seen in profile?&#10;A) Greater tuberosity&#10;B) Acromioclavicular joint&#10;C) Lesser tuberosity&#10;D) Coracoid process

Accepted Answer

The lesser tuberosity is typically seen in profile on certain shoulder radiographs, indicating its correct identification.

Question 4

&#10;&#10;-What view helps determine the relationship of the humeral head to the glenoid fossa, in the setting of a suspected glenohumeral joint dislocation?&#10;A) Anteroposterior of the shoulder&#10;B) Lateral view of the scapula&#10;C) Acromioclavicular bilateral view with and without weights&#10;D) Axillary view of glenohumeral joint

Accepted Answer

The axillary view of the glenohumeral joint is specifically designed to provide a clear image of the relationship between the humeral head and the glenoid fossa, which is crucial for diagnosing dislocations of the glenohumeral joint.

Question 5

&#10;&#10;-Refer to the figure. Name the imaging modality.&#10;A) MRI&#10;B) Radiograph&#10;C) Arthrogram&#10;D) 3D CT

Accepted Answer

The figure likely shows a 3D representation of anatomical structures, which is characteristic of a 3D CT scan.

Question 6

&#10;&#10;-Refer to the figure. Describe the pathological condition.&#10;A) Osteolytic destruction&#10;B) Degenerative joint disease&#10;C) Fracture of the scapula&#10;D) Dislocation of the glenohumeral joint

Accepted Answer

The answer of  &#10;&#10;-Refer to the figure. Describe the...

Question 7

&#10;&#10;-Refer to the figure. Identify the imaging modality and plane.&#10;A) Oblique coronal MRI&#10;B) Coronal MRI&#10;C) Oblique coronal CT&#10;D) Coronal CT

Accepted Answer

The answer of  &#10;&#10;-Refer to the figure. Identify the...

Question 8

&#10;&#10;-Refer to the figure. Contrast has been added to the ______________joint. This procedure is called _________________.&#10;A) glenohumeral; myelography&#10;B) acromioclavicular; arthrography&#10;C) coracoclavicular; arthrography&#10;D) glenohumeral; arthrography

Accepted Answer

The correct answer is D) glenohumeral; arthrography. This procedure involves injecting contrast into the glenohumeral joint, which is part of the shoulder, and is known as arthrography, a technique used to visualize joints.

Question 9

&#10;&#10;-Refer to the figure. The most common reason this image is made is to identify:&#10;A) Occult or stress fractures&#10;B) Osteochondritis dissecans&#10;C) Labral or ligamentous tears&#10;D) Glenohumeral dislocations&#10;

Accepted Answer

The image referred to in the question is likely a type of medical imaging, such as an X-ray, MRI, or CT scan, which is commonly used to diagnose various musculoskeletal conditions. The most common reason for creating such an image would be to identify occult or stress fractures. Occult fractures are fractures that are not visible on standard X-rays and may require more advanced imaging techniques to be detected. Stress fractures are tiny cracks in a bone that occur over time due to repetitive force, often from overuse, such as repeatedly jumping up and down or running long distances. Imaging is crucial for diagnosing these types of fractures to ensure proper treatment and healing.

Question 10

The most common rotator cuff tear involves the hypovascular critical zone of the _______________, 1 cm proximal to its insertion on the _______________________.&#10;A) infraspinatus; lesser tuberosity&#10;B) teres minor; surgical neck&#10;C) supraspinatus; greater tuberosity&#10;D) subscapularis; greater tuberosity

Accepted Answer

The most common rotator cuff tear involves the supraspinatus tendon, particularly in its hypovascular critical zone, located approximately 1 cm proximal to its insertion on the greater tuberosity of the humerus.
