Objective . To evaluate planned and obtained results of implantation of pedicle screws using individual navigation templates in patients with degenerative diseases of the lumbar spine. Materials and methods . Based on the results of computed tomography, the safety and accuracy of installing pedicle screws (30 patients, 126 screws) were analyzed using individual navigation templates. Results . The degree of safety 0 is registered in 96% (121 screws), the degree 1 is in 4% (5 screws). There were no cases of bone perforation by more than half of the screw diameter. There were no significant differences in the standard deviation of the sagittal angle between the planned installation and the actual trajectory of the screw. In the axial plane, no significant differences in standard deviation were observed at the entry and expected exit points of the screw. Statistical analysis showed insignificant differences between the planned and actual results (p>0.05) Conclusion . The use of individual navigation templates makes it possible to implant pedicular screw structures in the lumbar spine with a high level of safety and accuracy.
