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 A fractures involve pure compressive injury to a vertebral body of the anterior column. The authors are from multiple institutions in Europe and North America.
Since the anterior longitudinal ligament and posterior vertebral elements are intact, these fractures tend to be stable in extension.
