B3 Anterior tension band injury

Definition

Type B3 is an anterior tension band injury.

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

There is physical disruption or separation of the anterior structures (bone/disk) with tethering of the posterior elements.

These injuries may pass through either the intervertebral disk or through the vertebral body itself (as in the ankylosed spine). An intact posterior hinge will prevent gross displacement
