The vertebral artery has two 90 degree turns in the bone in the lateral region of C2. The first involves a lateral 90 degree turn and the second a cephalad ninety degree turn at the level of the lateral edge of C2 vertebral body. Injury to the vertebral artery is a potential complication of screw fixation into C2. The vertebral artery is caudal to the pedicle of C2 and lateral to the pedicle of C2. The carotid artery is immediately anterior to the lateral masses of C2.
