Odontoid fractures are rarely seen in childhood. Treatment is different than in adults and diagnosis is difficult. Our case was a 5-year-old male. He was admitted to emergency department after a traffic accident. He had neurological deficits. We noticed odontoid fracture and anterior dislocation on cervical computed tomography (CT). Odontoid screw fixation was done via anterior approach. However, the odontoid screw was removed in the postoperative early period due to breakage of the front part of C2 corpus and he was kept in cervical collar. In radiological follow-up, the odontoid fracture healed with conservative measures. Unlike adults, childhood odontoid fractures result in high rates of solid fusion with external fixators. These fractures are called “joints shift” or “synchondrotic slip” and surgery should be planned if nonunion develops despite conservative treatment or if there is compression of neural structures, unstable spine injuries, odontoid dislocations greater than 4 mm, type IC synchondrotic fracture and neurological impairment due to brain or spinal cord injury, as well as multiple trauma. Management of synchodrotic fracture of the odontoid is still controversial. Both surgical stabilization and closed reduction plus external immobilization could be the treatment of choice for unstable odontoid fracture in this age group.
