B2 Posterior tension band injury (bony capsuloligamentous, ligamentous)

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

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

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.

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.
