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.
The transverse ligament and the anterior arch of C1 are not involved, making this fracture stable. Initial management involves the differentiation of this benign fracture from a Jefferson fracture. Once this is accomplished, only use of a cervical orthosis is required.
