Type A1 injuries are compression fractures involving a single endplate without involvement of the posterior wall of the vertebral body. A-type injuries are in general a failure of anterior structures under compression with intact tension band.
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.
CT/radiograph images are examined to determine the fracture type.
This CT show a sagittal reconstruction of an C7 superior endplate A1 fracture.
For a complete classification (AOSpine Cervical classification) of the injury, and for the management decisions, the following aspects must be considered.
