Figure 2

A 47-year-old male patient was admitted to our hospital due to neck pain and restricted neck motion for 2 h from falling from a height. Preoperative three-dimensional CT scanning (A), X-ray (B), and MRI (C) showed that anterior ring and hangman's fracture. He underwent posterior atlantoaxial pedicle screw internal fixation. Postoperative anteroposterior (E) and lateral (F) X-ray showed that the atlantoaxial fracture was fixed well by the posterior atlantoaxial pedicle screw. At 9 months of follow-up, the anteroposterior (G) and lateral (H) X-ray showed that the fracture was healed well.
