Flashcards in cervical spine imaging Deck (14):
1

what is adequacy

ensure you can see occiput to T1

2

what is aligment

presence of correct lordotic curve

3

name the ligmants of the neck

ligamentum nuchae
posterior and anterior longitudinal ligaments
interspinous ligament
supraspinous ligament

4

what lines indicate the aligment of the cervical spine

posterior tip of spinous process

lamina junctional line

posterior vertebral bodies

anterior vertebral bodies

5

describe the prevertebral facia

allows gliding
extends down to T3
covers floor of the posterior triangle
cervical and brachial plexus
3rd part of the subclavian artery

6

what is the epidemiology of spinal injury

80% male

45% cervical. 25% thoracic

50% RTA 30% fall, 20% sports

7

what signs mean that the patient does not need a cervical spina x ray

if alert and stable, and:
• <65 years old
• Not serious mechanism of injury
• No tingling/sensory symptoms
• Was involved in rear-end shunt
• Sitting up
• Ambulatory since injury
• Delayed onset neck pain
• No cervical midline tenderness
• Able to rotate head 45 degrees either way.

8

what are the most common mechanisms of injury

flexion
extension
compression
combination

9

what are odontoid peg fractures

fractures of the cervical spine

10

what is anterolisthesis

the upper vertebral body slips forward onto the vertebra below

11

what are the features of a flexion injury

severe kyphosis
teardrop fragments
anterolisthesis
disrupted posterior vertebral body line
wider interlaminar space
narrow disc space above involved vertebra

12

Compression, burst injury

Severe compressive force that explodes
the vertebra
Compression of the vertebral body
Disruption of the posterior body line
Widening of the interpedicular distance

13

extension injury

•Wide disc space below involved
vertebra
•Triangular avulsion fracture
inferiorly
•Retrolisthesis
•Neural arch and/or pillar fracture

14

radiological interpretation sequence

adequacy
alignment
bones
cartilages and joints
soft tissues- retropharyngeal space, peripheral soft tissues
