Abstract: Pedicle screw fixation is biomechanically most reliable for reconstruction of the cervical spine, which can ef⁃ fectively restore cervical sagittal profiles, provide rigid fixation and higher fusion rate. Because of the large individual differ⁃ ences in cervical pedicle, vertebral artery and nerve root, preoperative evaluation should be individualized. Cervical pedicle screw techniques include freehand technique and the computer-assisted navigation technology developed recently. Although complications associated with cervical pedicle screw fixation cannot be completely obviated, they can be minimized by com⁃ bination of sufficient preoperative imaging studies of the pedicles and meticulous surgical techniques of screw placement. Cervical pedicle screw fixation techniques have been used in the treatment of various cervical disorders, with fewer complica⁃ tions and good clinical efficacy, and a wide range of clinical applications.
