A Jefferson fracture is a bone fracture of the vertebra C1. The vertebra C1is a bony ring, with two wedgeshaped lateral masses, connected by relatively thin anterior and posterior arches and a transverse ligament. The lateral mass on vertebra C1, who is taller, is directed laterally.
Both the anterior and posterior ligamentous structures are injured, which may not be the case in a burst fracture. Burst fractures, however, can have associated injury to the posterior ligamentous structures, especially if there is a combination of axial loading and flexion at the time of injury. Most common site of injury to the spine is the thoracolumbar junction.
