About This Document

 

A..  Lateral c-spine - keep hard collar on.

- adequacy of film - see all of C7, top of T1. If "No" -

continue anyway. Repeat films if no fracture.

- Alignment -  Fig. 1 - line 1 - continues along ant. odontoid

- Line 2 - continues along posterior odontoid

- Line 3 – connects laminae

- Line 4 note C1 should not reach this line

 

- Soft tissue thickness < 5 mm at C2 a <22 mm at C6

- atlanto-odontoid space: 3 mm or less

- Bones - check for fractures. Shape of C3-C7 vertebral body should be approx. the same as the one above and below.

 

If a fracture is seen - do no further views - immobilize and transfer

 

B. If lateral is normal, remove immobilization and proceed with more views

 

Odontoid view: Fig. 2

- Alignment of lateral masses (arrows)

- Odontoid fracture - 3 types shown

 

PA view: Fig. 4

- Alignment of spinous processes only

 

C. Obliques -Useful for unilateral facet dislocations  -Foraminae all intact  Fig.3

- Laminae line up like"shingles on a roof"

 

D. Flexion-extension views -for further reassurance if other views normal. Use lat c-spine checklist. Some injuries not obvious on initial lateral will be visible on a lateral view.
