The use of the pedicle screw system has become increasingly popular for treating an unstable cervical spine resulting from traumatic, degenerative, inflammatory, and neoplastic conditions. Because the cervical pedicle screw (CPS) has superior bio mechanical stability as the lateral mass screw or trans articular screw , pedicle screws allow for shorter instrumentation with improved spinal alignment. However, CPS insertion is technically demanding because of the anatomical variations in cervical pedicle size, lack of anatomical landmarks, small pedicle diameter, and the large transverse angle of cervical pedicles . The potential risk of injury to neurovascular structures, such as the vertebral artery, spinal cord, or nerve roots, caused by CPS remains a great concern. Therefore, accurate and safe CPS insertion techniques are necessary.
