1. IntroductionIn 2004, Wright described the C2 translaminar screw fixation, which involves the insertion of bilateral screws into the lamina of C2 in a crossing fashion that is then connected to C1 lateral mass screws. Wright states that anatomic variability of the foramen transversarium in the body of the axis can preclude safe transarticular C1 - C2 screw placement in up to 20% of patients and C2 screw fixation with pedicle screws remains a significant risk to the vertebral artery.
