Biomechanical evaluation of In-Out-In pedicle screws for atlantoaxial posterior fixation in the presence of high-riding vertebral artery and narrow C2 pedicles: a finite element analysis

Abstract Introduction In patients with high-riding vertebral artery (HRVA) and narrow pedicles, placement of C2 pedicle screws carries a significant risk of vertebral artery injury. The in-out-in pedicle screws (IOIPS) technique offers an alternative posterior fixation strategy. However, the biomech...
