Flashcards in Trauma Imaging Review Deck (31):
1

What is trauma?

-A sudden, unexpected dramatic event
-Incorporates a range of conditions

2

In trauma imaging, how does one approach the standard projections that are part of the routine protocol for imaging different body parts?

Adaptation (to patient)

3

What are the differences among the four levels of hospitals?

Level 1 –
Level 2 –
Level 3 –
Level 4 -

4

***What are the different types of forces associated with trauma imaging?

-Blunt trauma (MVA, collisions, falls & aggravated assault)

-Penetrating trauma (gun shot wounds, stab wounds, impalement injuries, foreign body ingestion & aspiration)

-Explosive trauma (pressure shock waves, high-velocity projectiles & burns)

5

***What is Principle 1 for trauma imaging?

2 projections 90 degrees to each other with true CR-part-IR alignment
-Angling of CR and IR as needed
-Consider patient’s condition

6

***What is Principle 2 of trauma imaging?

Entire structure is included on image
-Selection of IR size
-Secondary fractures
-Joint nearest fracture site

7

What is Principle 3 of trauma imaging?

To maintain safety for patients, healthcare workers and the public
-Side rails
-ALARA principle

8

Fracture Terms 9-29:

-Dislocation or luxation



-Bone displaced from joint

9

***-Subluxation or partial dislocation

-Abnormal shape or alignment

10

Sprain

Twisting of a joint resulting in partial rupture or tearing of ligaments w/o dislocation

11

Fracture

Break in a bone

12

Apposition

Alignment or disalignment describing the relationship of the long axes of fx fragments

13

Anatomic apposition

Fragmented ends make end-to-end contact

14

***Lack of apposition or distraction

Fragmented ends are aligned but pulled apart

15

Bayonet apposition

Fragments overlap and shafts make contact (fracture ends do not)

16

Angulation

Loss of alignment of fracture

17

Apex

Direction or angle of apex of fracture

18

***Varus deformity

Distal part of distal fragment angled toward midline of body (lateral apex – points away)

19

Valgus deformity

Distal part of distal fragment angled away from midline (apex pointed toward midline)

20

***Simple/closed

Bone does not break through skin

21

Compound/open

Portion of bone protrudes through skin

22

Incomplete

Fracture does not traverse through entire bone

23

Complete

Break is complete and broken into 2 pieces

24

Torus or Buckle

Buckling of cortex with localized expansion and no complete break in cortex

25

Greenstick

Fracture on one side only with the other side bent

26

Transverse fracture

Near right angle to long axis of bone

27

Oblique fracture

Fracture that passes at an oblique angle to long axis of bone

28

Spiral fracture

Bone is twisted apart and fracture spirals around long axis of bone

29

Cast Conversion 30-32:

-Fiberglass cast



-Increase kVp by 3-4kV

30

***Small to medium plaster cast

Increase kVp by 5 to 7 kV

31

Large plaster cast

Increase kVp by 8 to 10 kV
