I have seen a lot a B3 fractures in the cervical and thoracic areas, particularly in patients with DISH, but as we know the are small differences between a B3 and C fracture patterns and it is possible to turn a B3 fracture to a C just during patient positioning.

I am looking for more answers than just the description of both patterns, more differences than just hyperextension (B3) and traslation (C), What other features matter in the classification or should be considered? Both are unstable patterns so why not to consider a B3 just a subgroup of C patterns..
