Abstract:

BACKGROUND: CT evaluation and scanning before and after thoracic pedicle screw implantation can improve the accuracy of screw placement, and can avoid the serious complications caused by nerve and blood vessel injury during screw implantation.
OBJECTIVE: To in-depth analyze CT evaluation and application for thoracic pedicle screw implantation, and to provide relevant reference information for improving pedicle screw implantation technology as well as the research and application of CT scans in the field.
METHODS: The SCI database from 2002 to 2011 was searched for the articles on the CT evaluation for thoracic pedicle screw implantation, and the bibliometric analysis and experimental research and analysis were performed on these articles. We analyzed the author, institute and the countries of the articles in order to clear the research on this field worldwide. The feasibility, accuracy, risk of structure anatomy and the clinical application of CT evaluation for thoracic pedicle screw implantation were analyzed, and the application range of CT scanning for thoracic pedicle screw implantation was indentified.
RESULTS AND CONCLUSION: The CT scan evaluation for thoracic pedicle screw implantation has a high accuracy. The CT scanning for the thoracic pedicle and adjacent structures around the screw placement before implantation can evaluate the morphology of the thoracic pedicle and the structural relationship with the surrounding tissue, improve the accuracy of screw implantation and avoid the complications caused by neurovascular injury. The CT scanning for the thoracic pedicle and screw system after implantation can evaluate the effect and satisfaction of screw implantation, in order to provide the assistance for developing follow-up treatment programs.
