From the case:
Os odontoideum
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/67364/annotated_viewer_json?iframe=true\u0026lang=us"}
No evidence of fracture.
The findings from the previous radiograph are confirmed. There is moderate posterior subluxation of C1/C2, suggesting atlantoaxial instability.
Case Discussion
The findings are in keeping with os odontoideum.
