Jefferson Fracture


Burst fracture of the atlas (C1). Often occurs as a result of an axial load to the spine from a direct blow to the vertex of the head

C1 is compressed between the occipital condyles and C2, resulting in lateral spread of the C1 articular masses and consequent fractures of both the anterior and posterior arches of C1
