Rights and Permissions

Aberrant vertebral arteries at C1 and C2 facet regions are rare. These vessels can pose challenges while inserting screws into the lateral mass. However, mobilization of these vessels is possible to obtain specific screw entry points. In normal bony anatomy, these aberrant vessels are tortuous and hence can be mobilized quickly. Multiple screw entry points are available for safe screw placement. Aberrant vessels at this region do not preclude the placement of screws in lateral mass.
