1

This is the MC atlas fracture

Posterior Arch fracture

2

What are the reasons the C1 spinolaminar line can be too far anterior

1. Posterior Arch Fracture
2. TAL rupture
3. Dens fracture

3

What film can confirm a posterior arch fracture

flexion/extension

4

A posterior arch fracture can also cause

an increased anterior tubercle

5

Is a posterior arch fracture usually bilateral and vertical

Yes

6

This fracture can be seen on film by noticing bilateral lateral mass offset

Jefferson's Fractures

7

This is a fracture of both the anterior and posteriro arches of C1

Jefferson's Fracture

8

If a Jefferson's fracture is combined with this, it can become unstable and compress the brain stem and can cause brain damage

torn Transverse ligament of >7mm

9

ADI range for adults

10

ADI range for kids

11

This is the best film to see an increased ADI

Flexion

12

Steele's Rule Of Thirds

Divide the atlas into thirds
1/3 cord
1/3 dens
1/3 potential space
Anterior displacement may be asymptomatic

13

This is 40-50% of all axis fractures

Odontoid Fractures

14

This type of odontoid fracture is oblique and through the tip

Type I
(Rare/Stable)

15

This type of odontoid fracture is at the base of the odontoid

Type II
(unstable)

16

This type of odontoid fracture is in the body of the C2

Type III
(unstable/stable)

17

These odontoid fractures both heal well

Type I and II

18

This odontoid fracture causes a disruption of Harris' ring

Type III

19

The ligament that can be involved with a Type I odontoid fracture

Alar ligament

20

Most old os odontoideum are old

un-unitd dens fractures

21

This fracture can cause a "fat C2 body"

Type III odontoid fracture

22

Type III odontoid fracture is best seen on this film

Lateral

23

This is a bilateral pedicle fracture of C2

Hagman's fracture

24

Hagman's fracture usually occurs from this mechanism

Hyperextension

25

This is the MC fracture of the spine we can see

Compression fracture

26

Compression fracutres have this effect on vertebral body

Decreased anterior body height

27

Compression fractures usually occur from this mechanism

Flexion

28

This fracture is when a vertebral body "explodes" into several fragments

Bursting Fracture

29

Bursting fractures are usually this type of compression

axial

30

Bursting fracctures are MC in this portion of the spine

cervicals
lumbar

31

Radiological findings of a bursting fracture on an AP view

vertical split of the body

32

Radiological findings of a bursting fracture on a lateral

comminuted body flattened centrally

33

A bowtie sign is usually associated with this

Unilateral Facet Dislocation

34

What happens to the inferior articular pillars in a unilateral facet dislocation

they go into the IVF

35

Unilateral facet dislocation is assocaited with this type of motion mechanism

flexion/extension

36

Spinous rotates to which side in a unilateral facet dislocation

to the side of dislocation

37

Hamburger sign is seen on this imaging

CT, Unilateral Facet Dislocation

38

Which films are needed to done to confirm unilateral facet dislocation

Obliques

39

Where are the MC segments for bilateral facet dislocation

C4-7

40

This is the most severe injury to the cervical spine

Flexion teardrop fracture

41

This fracture has a triangle fragment at the anterior, inferior body

Flexion teardrop
Extension teardrop

42

Flexion teardrop fracture can cause this syndrome

Anterior Cord Syndrome

43

Extension teardrop fractures usually occur at this segment

C2

44

Extension teardrop fracture has a buckling on this ligament

ligamentum flavum

45

This fracture can be seen at the base of the spinous

Clay shovelers

46

What segements are usually affected by Clay Shovelers fracture

C6-T1

47

Clay Shovelers fracture is associated with this motion mechanism

Flexion

48

Clay Shovelers fracture shows this finding on a AP film

Double Spinous Sign

49

Pillar Fractures are usually in these segments

C4-7

50

Pillar fractures are associated with this motion mechanism

Extension/Compression

51

Whiplash can affect this ligament complex

Posterior Ligament Complex

52

90% of Thoracic/Lumbar fractures are in which segments

T11
L2

53

What findings can be seen on a Thoracic/Lumbar fractures

Anterior wedging (decreased anterior height)

54

What is a zone of impaction

A dense white band just below the compresses endplate in thoracic/lumbar fractures

55
