1

Nondisplaced fracture only visualized on ___ view 

Oblique

2

The following is what imaging modality

CT

3

____ is the preferred modality for traumatically induced internal drangment of joints & soft tissues (including spinal cord & nerves)

MRI

4

Entire circumference of the bone is disrupted = ____ fracture

Complete

5

Involves only part of the cortex (seen MC in children or in smaller bones such as distal radius or ulna) = ____ fracture

Incomplete

6

This is an example of a ____ (complete/incomplete) fracture

Complete

7

This is an example of what kind of fracture

Incomplete - Greenstick (generally only occure in skeletally immature population)

8

This is an example of what kind of fracture?

Incomplete - Torus (aka buckle, generally occurs in skeletally immature)

9

This is an example of what kind of frature?

Incomplete - Stress

10

____ fractures are a result of tension and/or angular forces

Transverse

11

This is an example of a ____ fracture

Transverse

12

____ fractures are a result of compressive forces

Oblique

13

This is an example of ____ fracture

Oblique

14

____ fractures are a result of rotational forces

Spiral

15

The following is an example of ____ fracture

Spiral

16

More than two fragments = ____

Only two fracture fragments = ____

Comminuted

Non-comminuted

17

This is an example of ____ (comminuted/non-communited) fracture

Non-communited

18

This is an example of ____ (comminuted/non-communited) fracture

Communited

19

The degree of contact at the fracture site between the fragments = ____

Apposition

20

Describe the apposition of the following image

Good

21

Describe the apposition of the following image

No (poor) apposition - Distraction

22

Describe the apposition of the following image

No apposition - Bayonet

23

Describe the angulation of the following image

Posterior angulation of the distal aspect of distal fragment

24

Describe the angulation of the following image

Lateral angulation of the distal aspect of the distal segment

25

This is an example of what type of abnormal alignment

Rotation (external rotation of distal aspect)

26

This is an example of what kind of fracture

Intra-articular

27

Used to describe Impaction fractures of EXTREMITIES

When a harder bone impacts a less dense bone & depresses the surface; common location is the tibial plateau

Depression

28

Used to describe Impaction fractures in SPINE

Impaction of bone causes loss of height because of telescopnig trabelua; typically appears as incrased density (linear sclerosis) on radiographs

Compression 

29

This is an example of what kind of fracture

Depression

30

This is an example of what kind of fracture

Compression
