Posterior tension band injury

Type B injuries include failure of the posterior or anterior tension band through distraction with physical separation of the subaxial spinal elements while maintaining continuity of the alignment of the spinal axis without translation or dislocation.

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

In the cervical spine this is a very uncommon injury.

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