B2

B-type injuries are in general a failure of the posterior or anterior tension band.

Type B2 is a complete disruption of the posterior capsuloligamentous or bony capsuloligamentous structures together with a vertebral body, disk, and/or facet injury.

Combine with Type A fracture type and facet type injury classification when appropriate.

This always involves a motion segment and should be called an injury of eg. C5/C6.


X-ray/ CT

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

This CT show a sagittal reconstruction of an C7/T1 ligamentous B2 injury without a fracture.


This image show a sagittal MRI 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

Patient examination

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