[The odontoid bone. Apropos of a surgically treated case].
An odontoid bone was detected in an adult patient after injury to neck, with secondary appearance of disorders related to C1-C2 instability that disappeared after posterior C1-C2 arthrodesis. The odontoid bone is a rare anomaly of debatable origin. Current pathogenicity theories are discussed.
