Figure 1: Images of a 23-year-old male. (a) Computed tomography scan with the head in flexion shows assimilation of atlas, C2–3 fusion, increased atlantodental interval and fusion of vertebral bodies C6–T3. (b) Computed tomography scan with the head in extension shows vertical atlantoaxial instability and mild reduction of dislocation. (c) T2-weighted magnetic resonance imaging shows compression of the neural structures opposite the odontoid process. (d) Computed tomography scan with the cut passing through the facets showing atlantoaxial facetal instability. Omovertebra can be seen arising from C5 vertebral body in the region of the transverse process. (e) Three-dimensional computed tomography scan showing the large omovertebra arising from the C5 body and travelling toward the scapula. (f) Photograph of the back of the patient showing the hump over the left shoulder made by the underlying omovertebra. (g) Postoperative computed tomography scan showing reduction of the instability and fixation. (h) Postoperative computed tomography scan image through the facets showing the implant
