Clinical Application of a Revised Screw Technique via the C1 Posterior Arch and Lateral Mass in the Pediatric Population

Abstract

The PET is an effective alternative for pediatric AAI when the height of the C1 posterior arch is <4 mm. Because of the higher screw entry point through the C1 posterior arch, there is effective biomechanical stability and less irritation of the venous plexus and C2 nerve root.
