Question 8

What are X-Rays good for visualizing and whne should they be ordered?

Answer 8

Bones (also chest pathologies)

first, before any other test

super cheap $

Question 9

When should you order a CT scan and what are they good at imaging?

Answer 9

After an X-Ray or if you need to view:

Brain injuries, organas, fractured bones

Affordable $$

Question 10

When should you order an MRI and what does it help you visualize?

Answer 10

LAST! Very expensive $$$

For viewing:

Joint injury

ligements, tendons, visceral organs, bones

Question 11

What clinical pathology is this showing?

Answer 11

SLAP Tear

• Caused by overuse of the biceps brachii where the tendon will ultimately pull away par of the labrum away from the glenoid fossa (TRAUMA, OVERUSE)
• Common in athletes
• SUPERIOR aspect of the labrum tears

ONLY CAN VIEW ON MRI

Question 12

What clinical pathology is this?

Answer 12

Anterior Labroligamentous Periosteal Sleeve Avulsion (ALPSA)

• Similar to SLAP but this is not an injury from overuse. Rather, it is associated with RECURRENT DISLOCATIONS
• INERFIOR aspect of the labrum tears

Question 13

What clinical pathology is this?

Answer 13

Hill-Sachs Deformity

Anterior dislocation leads the posterior portion of the humeral head to rub on the glenoid fossa, creating a divot in the head of the humerus.

Associated with: Recurrent Dislocations

Question 14

What clinical pathology is this?

Answer 14

Sail Sign

-Anterior Displacement of the Radial Fat Pad

Adults: Caused by radial head fractures

Children: Caused by supracondylar fractures

Question 15

What clinical pathology is this?

Answer 15

Scaphoid Fracture (left, lower bone)

Get MRI after a couple weeks to see since often won’t show up on X-Ray

Question 16

What clinical pathology is this?

Answer 16

Torn ACL (Left)

You can tell by the “Frowny-Face” it has compared to the right, which goes superiorly and posteriorly
