case_images: Left parasagittal (a) and coronal (c) CT scan images show a right nondisplaced impaction occipital condyle fracture (arrow), classified as Anderson and Montesano type I and Tuli type 1. Right parasagittal CT image (b) shows an occipital condyle-C1 interval of 2.5 mm (double-headed arrow) and a 5 mm translation of C1-C2 (asterisk).

case_images: Computed tomography of her cervical spine showed a left nondisplaced impaction OCF with an occipital condyle-C1 interval of 2.5 mm and a 5 mm translation of C1-C2 (Figure 1).
case_images: Left (a) and right (b) parasagittal CT scan images demonstrate complete reduction of both the atlantooccipital joint and the atlantoaxial joint.

case_images: After reduction, computed tomography was performed and we confirmed the complete reduction of both the atlantooccipital joint and the atlantoaxial joint (Figure 2).
case_images: Postoperative radiograph shows occipitocervical fusion achieved by an occipital plate and bilateral C2 pedicle screws.
