Figures
- FIG. 1
Failure of segmentation of the cervical spine in a 5-year-old child (patient 4) demonstrating 5 mm of C1–C2 instability (black arrows). White arrows depict the anterior tip of the atlas, which is subluxated forward.
- FIG. 2
Hypoplastic odontoid process in a 15-year-old patient (no. 7).
- FIG. 3
Extension (left) and flexion (right) views of the cervical spine of patient 8, lllustrating C1–C2 instability at 3 years of age. Black arrows = platybasia of the occiput, white arrows = anterior subluxated portion of the atlas.
- FIG. 4
Cervical occipital fusion for C1–C2 instability and occipitalization of C1 in a 4-year-old girl (patient 1).
