Biomechanical comparison of three C2 subfacetal screw trajectories: a finite element analysis with reference to established posterior atlantoaxial fixation techniques

C2 subfacetal screw fixation has emerged as a crucial alternative for atlantoaxial instability when a high-riding vertebral artery (HRVA) precludes the use of conventional C2 pedicle screws. However, a comprehensive finite element analysis focusing on the biomechanical variances...
