Magerl et al developed a classification for injuries to the thoracic and lumbar spine using a scheme similar to that used for the AO fracture classification. The Type C fractures involve (a) injury to the anterior and posterior elements together with (b) rotation. The authors are from multiple institutions in Europe and North America.
Type C injuries cause complete loss of the tensile strength of the spine. These injuries are unstable in axial torque and may be superimposed on Type A and/or Type B injuries. They result in the highest rate of neurological deficits and require surgical stabilization.
Major subtypes:
(1) compression injuries (Type A) with rotation
(2) flexion-distraction injuries (Type B1 and B2) with rotation
(3) hyperextension-shear (Type B3) with rotation
(4) mixed rotation and shear
