The current study's objective was to contrast the accuracy of C2 navigation template-assisted versus free-hand pedicle and/or pars screw fixation in high-risk cases where a high-riding vertebral artery or narrow pedicle and complex deformities were associated.In our hospital, CT data of 30 subjects with pathology on COur results stated that the accurate placement rate is not noticeably different between navigation template-assisted and free hand pedicle screws, where the HRVA and narrow pedicles associated, but was better in navigational template group with complex deformities. Pars screws were found to be superior in terms of accuracy.The current study suggests that navigational template assisted pedicle screws are risky for high-risk individuals with abnormal anatomy, such as those with a high-riding vertebral artery, a narrow pedicle, and complex abnormalities, and alternative C2 pars screws may be a reliable option for such individuals. |
