A0 - Minor, nonstructural fractures

Type A0 is used to describe insignificant fractures not affecting the spinal stability in a significant way, such as an isolated fracture of the spinous process, the transverse process or the lamina.

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

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

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

This CT show a transverse image of the same injury.

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
