Type III (C) ventral subluxation of atlas in both joints, atlas anterior displacement greater than 5 mm, deficient transverse and alar ligaments. Type IV (D) dorsal subluxation of atlas, posterior atlas displacement and deficient odontoid process; possible fractured Dens axis or congenital Dens-aplasia.
