Background:
Navigation surgical systems have been widely used in spinal fusion to ensure accuracy and safety during pedicle screw insertion.
Methods:
The research was performed under laboratory conditions, using stereotactic navigation, surgical instruments for spinal fusion, development of additional devices and software. During the experiments, all stages of the computed tomography-guided navigation system use were performed-preoperative preparation of patient data and planning to provide visual control of the navigation of surgical instruments during the insertion of screws.
Results:
The 20 screws were inserted into the vertebrae of the lumbar spine phantom with an average pedicle width of 12.6 ± 1.29 mm with 100% clinical accuracy. The 30 screws were inserted into cadaveric sheep vertebrae with an average pedicle width of 6.56 ± 0.58 mm with 96.67% efficiency.
Conclusions:
The proposed navigation technique of the CT-guided navigation system is highly effective in the navigation process of surgical instruments and pedicle screws during spinal fusion.
