Type A3 injuries

 X-ray/ CT
 Patient examination

A-type injuries are in general a failure of anterior structures under compression with intact tension band.

Type A3 is a burst fracture involving a single endplate (superior or inferior) with involvement of the posterior vertebral wall.

Caution: If this fracture is seen at the cervicothoracic junction, it is likely that this is part of a type B or type C injury.

X-ray/ CT

CT/radiograph images are examined to determine the fracture type.

This CT show a sagittal reconstruction of an
C7 burst A3 fracture.

For a complete classification (AOSpine Cervical classification) of the injury, and for the management decisions, the following aspects must be considered.

  1. Neurology
  2. Facet injury
  3. Clinical modifiers

Patient examination

A standardized clinical evaluation is highly recommended before fracture treatment. Moreover, specifically in Spine injuries neurological evaluation is mandatory.
