Where plain radiography is indicated, three films are taken of the cervical spine: lateral, anteroposterior (AP) and open mouth (peg) views.
This combination allows for good visualisation of the entire cervical spine. A lateral view in isolation will only detect 75% of c-spine injuries.
The x-rays can be interpreted using the ABCD system:
Adequacy/Alignment
Bones
Cartilage
Dense soft tissues
Learning Bite
All plain radiographs of the spine may be assessed using the ABCD system.
