Applied anatomic studies of cervical anterior transpedicular screw fixation
Objective To provide relevant anatomic parameters for the promotion of the Cervical anterior transpedicular screw fixation(ATPS). Methods 30 sets adult normal cervical specimens were randomly selected, and the scanned data were imported to the MIMICS 13.0 software；the related anatomical parameters and the pedicle screw parameters of ATPS were measured. Then the obtained data were subject to statistical anylysis. Rusults Through measurement the pedicle screw parameters, the best enterance point for screws and the best enterance channel for the screw could be determined. It could be found from the measurement that the height of the cervical vertebral pedicle was larger than the width and the the largest screw it can contain was 4.5 mm in diameter 30 mm in length. Conclusion ATPS can be applied to the treatment of cervical vertebra disease as a new fixation technology. It may provide a better help for the treatment of some cervical vertebral disease, such as tumor, serious osteoporosis and three-column injury of the cervical spine.
