Type B1 is a posterior tension band injury where the fracture line only goes through the bony structure.

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

In the cervical spine this is a very uncommon injury.

For a complete classification (AOSpine Cervical classification) of the injury, and for the management decisions, the following aspects must be considered.
