Abstract
Background:The anterior transpedicular cortical screw technique for the subaxial cervical spine represents a novel surgical fixation method for treating cervical spondylosis. Due to the complex anatomical structure of the cervical spine, screw placement presents certain technical challenges. Research on screw placement-related parameters will facilitate the widespread clinical application of this technique. Objective: This study aimed to visualize and determine the optimal trajectory for placing cortical bone screws in the lower cervical spine (C3-C7) via an anterior approach, providing anatomical data for clinical application. Conclusion: It is feasible to insert cortical pedicle screws via the anterior cervical approach, maximizing screw purchase on cortical bone.
