C2 pedicle screws. The pedicles of the C2 vertebra are directed toward the midline and in the cephalad inclination. Pedicle screws in this area impose a technical risk of injury to the vertebral artery laterally, the brain stem and dura medially, C2 nerve root in a cephalad direction and C3 nerve root in a caudal direction. Inferiorly the carotid artery is at risk for injury.
