All 12 cards

1. Card 1

   What is the primary difference in morphology between the distal part, body, and base of a digit?

   The distal part of a digit is rounded, the body is tapered, and the base is wide.

2. Card 2

   Describe the patient and part positioning for a PA projection of the 2nd to 5th digits.

   The patient should be seated at the end of the x-ray table. The hand should be pronated with fingers apart and extended. The Central Ray is directed perpendicularly to the PIP Joint.

3. Card 3

   What is the purpose of the Street Method for 2nd to 5th digits?

   The Street Method, which is a PA oblique projection with internal rotation, is used to increase recorded detail of the 2nd digit due to lower OID and to enhance the ability to detect specific fractures of the 2nd digit.

4. Card 4

   Which specific fracture is best demonstrated by the AP projection of the 1st digit?

   The AP projection of the 1st digit best demonstrates a Bennett's Fracture.

5. Card 5

   What is the key difference in Central Ray angulation between the Robert Method and the Long & Rafert Modification for the 1st CMC joint?

   In the Robert Method, the Central Ray is directed perpendicularly to the 1st CMC Joint, whereas in the Long & Rafert Modification, it is directed 15 degrees to the 1st CMC Joint.

6. Card 6

   What is the total number of bones in the hand, and how are they categorized?

   The hand has a total of 27 bones, categorized as 14 phalanges, 5 metacarpals, and 8 carpals.

7. Card 7

   What is the primary diagnostic application of the Folio Method for the 1st MCP joint?

   The Folio Method is best for demonstrating bilateral 1st MCP Joints and is used to diagnose UCL (Ulnar Collateral Ligament) Rupture or Skier's Thumb.

8. Card 8

   What is the purpose of the Lateral Extension projection for the hand, and what does it best demonstrate?

   The Lateral Extension projection is used to localize foreign bodies and provides a true lateral projection of the entire hand where all fingers are superimposed, and the 1st digit/thumb is in a true PA position.

9. Card 9

   Which projection is also known as the 'Ball Catcher's View' and what condition does it best demonstrate?

   Norgaard's Method, an AP Oblique Projection, is also known as the 'Ball Catcher's View' and best demonstrates Rheumatoid arthritis.

10. Card 10

    Describe the patient and part position for the Acute Flexion - AP Projection of the elbow (Distal Humerus – Jones Method).

    The patient is seated at the end of the x-ray table with the elbow fully flexed. The humerus is parallel with the IR, and the forearm is elevated. The Central Ray is directed perpendicularly to 2 inches superior or distal to the Olecranon Process.

11. Card 11

    What are the two variations of the PA Axial Projection for the distal humerus, and what does each best demonstrate?

    The two variations are for the Ulnar Sulcus and the Olecranon Process. The Ulnar Sulcus variation best demonstrates the Ulnar Sulcus and Tennis Elbow. The Olecranon Process variation best demonstrates the dorsal surface or the articular margin of the Olecranon Process, depending on the CR angulation.

12. Card 12

    What is the primary difference in structures shown between the AP and Lateral projections of the humerus?

    In the AP projection, the humeral epicondyles are parallel to the IR, and the humeral head and greater tubercle are in profile, with the lesser tubercle situated anteriorly. In the Lateral projection, the humeral epicondyles are perpendicular to the IR, the greater tubercle and humeral head are superimposed, and the lesser tubercle is situated medially.
