Diagnosis

Pseudosubluxation

Clinical Notes

Initially difficult to clinically evaluate. Subsequently found to be neurologically intact.

Findings

CT – Sagittal reformatted images demonstrate minimal apparent anterior translation of C2 vertebral body relative to C3; spinolaminar line is intact.

Discussion

Posttraumatic anterior subluxation of the cervical spine may be difficult to differentiate from “pseudodubluxation”. Pseudosubluxation is commonly observed in children. At C2-C3 this is seen in 19% of children between 1 and 7 years of age but can also be seen at C3-C4. Pseudosubluxation can be confidently diagnosed if the spinolaminar line is intact or divergent by less than 2 mm.
