“…In this drawing, a indicates ossiculum terminale of odontoid process, derived from proatlas ; b, odontoid process, representing original body of atlas, and c, axis, The genesis of atlanto-occipital fusion has been much discussed in the anatomic literature of the last two centuries.10 There are several possible causes responsible for bony union of the atlas with the occiput: In a small group of cases fusion is the result of a pathologic process (such as arthritis or tuberculosis) occurring in fetal or in early postnatal life (Sommer,11 Virchow,12 Le Double13).
