Anderson D'Alonzo Type I

The tip of the dens is obliquely fractured on one side. This rare fracture may be due to a shear injury when the tip of the dens comes into contact with the rim of the foramen magnum, however, it can also represent an avulsion fracture of the alar ligament and must therefore be seen as part of an atlantooccipital dislocation
