Abstract
The literature review presents data from world studies on the use of individual navigation templates in spine surgery and analyzes the published results of the application of individual navigation templates on different parts of the spine. The accuracy and safety of fixed transpedicular screws were evaluated using the templates. The main stages of template creation were highlighted, including the visualization methods for 3D modeling, 3D printing methods, available materials, as well as the time and costs associated with 3D printing were determined. For information analysis 23 publications were selected, 8 of them relate to the cervical spine, 10 — to the thoracic, and 5 — to the lumbar spine. The data of 460 patients in whom 3,294 screws had been fixed using the templates were analyzed, and the analysis has revealed that out of 3,294 screws, 3,059 (92.8%) have the highest level of safe fixation.
