case_images: On initial consultation, the patient could not move his head at all from its position facing to the right (Figure 1(a)). A lacerated wound (Figure 1(b)), about 1 cm in length, was observed over the right inferior mandible.
case_images: Computed tomography revealed that the atlas was rotated to the right centering on the dens of the axis. (a) Axial view of atlas and (b) axial view of axis.

case_images: Computed tomography (Figure 2) revealed that the atlas was rotated to the right centering on the dens of the axis.
case_images: The three-dimensional CT showed atlantoaxial rotatory fixation of Fielding classification type I. (a) Posterior view and (b) anterior view.

case_images: Based on a three-dimensional CT (Figure 3), we diagnosed AARF of Fielding classification type I without a protruding eccentric jaw position.
case_images: CT after reduction of atlantoaxial rotatory fixation. (a) Axial view of atlas, (b) axial view of axis, and (c) anterior view of three-dimensional CT.

case_images: MRI after reduction indicated no major soft tissue damages, and CT after reduction (Figure 4) showed that the dislocation had been reduced, so fixation with a Philadelphia collar was performed.
