From: Outcomes of surgery for unstable odontoid fractures combined with instability of adjacent segments
A 43-year-old male patient developed pain symptoms and paralysis of two lower extremities by traffic accidents. CT scanning indicated fractures of the odontoid process of the axis (A), combined with C1-2 and C2-3 dislocation (B). Anteroposterior (C) and lateral (D) cervical spine X-ray scanning showed excellent reduction after posterior C1-2 cervical pedicle screw and C3 lateral mass screws fixation. At 1 year after operation, the anteroposterior (E) and lateral (F) cervical spine X-ray scanning suggested bone fusion and no displacement of the implant.
