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

X-ray/ CT

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

This CT shows a sagittal reconstruction of an isolated spinous process fracture.

Diagnosis: X-ray/CT, A0 – minor, nonstructural fractures

This CT show a transverse image of the same injury.
