Abstract

The etiology of os odontoideum has been debated ever since its first description by Giacomini in 1886. There are proponents of congenital origin as well as reports of post-traumatic os odontoideum formation after early childhood craniovertebral junction (CVJ) trauma. We document CVJ ligamentous injury on MRI in an 18-month-old child with sequential imaging demonstrating the os odontoid formation. Our database of 260 surgically treated patients with os odontoideum was analyzed regarding etiology and associated abnormalities. The literature (1970-2022) is reviewed.
