Clinical Application of the “Pedicle Exposure Technique” for Atlantoaxial Instability Patients With a Narrow C1 Posterior Arch

Abstract

The "pedicle exposure technique" is an effective alternative in patients with the C1 posterior arch measuring <4 mm. In consideration of a high screw entry point on the C1 posterior arch, similar to the C1 posterior arch screw technique, we propose that this new technique can reduce venous plexus and C2 nerve root injury while providing effective biomechanical stability.
