Abstract:

BACKGROUND: Thoracolumbar pedicle screw fixation techniques play an important role in the development of spinal surgery, and spine computer navigation system can significantly improve the accuracy and safety of pedicle screws.
OBJECTIVE: To study the clinical application of pedicle screw fixation.
MESHODS: A computer-based retrieve was performed for the articles on the application of pedicle screw fixation and computer navigation technology in the fixation from January 1999 to December 2011 with the key words of “pedicle screw fixation, computer navigation technology, clinical application” in Chinese. Repetitive articles and Meta analysis articles were eliminated. Finally, 25 articles were included to discuss the research progress of pedicle screw fixation and relevant evaluation.
RESULTS AND CONCLUSION: Computer-aided surgical technique is a new technology that can help surgeons to make the surgery safer and accurately through virtual the surgical environment based on the high-speed processing of large amounts of data information and control capabilities of computer. Recently, we have achieved great development on the study of thoracolumbar pedicle screws technology, especially the intraoperative monitoring tool, it has developed from traditional X-ray fluoroscopy or radiography monitoring and positioning to visualize monitoring by computer-aided technology. Computer navigation technology can simulate and measure the length and angle of the pin tract and the diameter of pedicle from the three-dimensional image data stored in the computer, which is benefit to select the pedicle screw with the best length and diameter, so that to make the pedicle screw surgery more precise, simple, fast and safe and then reduce the occurrence of postoperative complications.
