Deck 16: Radiologic Evaluation of the Elbow

Question 1

-Refer to the figure. Name the projection.

A) Anteroposterior
B) Lateral
C) External oblique
D) Internal oblique

Answer 1

Lateral

Question 2

-A soft tissue sign associated with the projection in the question 1 figure is known as the fat pad sign. A positive fat pad sign is caused by:

A) Increased capsular volume
B) Extra adipose tissue
C) Poor radiographic positioning
D) Artifact

Answer 2

Increased capsular volume

Question 3

-A positive fat pad sign at the elbow would be correlated with what clinical finding?

A) Fractured forearm
B) Swollen elbow joint
C) Absent biceps contour
D) Triceps pain

Answer 3

Swollen elbow joint

Question 4

-An abnormal supinator line seen on the lateral radiograph of the elbow is a reliable soft tissue sign of an underlying:

A) Radial head fracture
B) Proximal ulna fracture
C) Medial epicondyle fracture
D) Lateral epicondyle fracture

Question 5

-An abnormal supinator sign seen on the elbow radiograph would most likely be correlated with what mechanism of injury?

A) Overuse in pitching
B) Painting a house
C) Fall on an outstretched hand
D) Rheumatoid exacerbation

Question 6

-Refer to the figure. Name the imaging modality and plane.

A) Anteroposterior MRI
B) Coronal MRI
C) Sagittal MRI
D) Axial MRI

Question 7

Refer to the figure. Is this a T1-weighted image or a fluid-sensitive T2-weighted image?

A) T1
B) T2

Question 8

-Refer to the figure. The increased edema at the origin of the common flexor tendon indicated by the arrow suggests:

A) Medial epicondyle fracture
B) Lateral epicondyle fracture
C) Medial epicondylitis
D) Lateral epicondylitis

Question 9

Radiographic evaluation of elbow trauma from a fall on an outstretched hand usually includes additional views of the:

A) Shoulder
B) Metacarpals
C) Forearm and wrist
D) Acromioclavicular joint

Question 10

Loose fracture fragments in the elbow joint can be difficult to see within the joint capsule. The best imaging morality to locate these fragments is:

A) Computed tomography
B) Magnetic resonance imaging
C) Bone scan
D) Ultrasound
