| Summary: | In case of complex injuries to the nerves of the upper limb during surgery in augmented reality and when creating artificial transplants, knowledge of the three-dimensional structure of the brachial plexus is necessary. The aim of this study is to develop a method for manufacturing maximally detailed and accurate hollow three-dimensional models of the brachial plexus from photopolymer resins. Material and methods. Using the developed technique, all elements of the right brachial plexus were dissected and isolated from 10 corpses of men and women aged 39–89 years, 3D scanning was performed, digital models were created, and 3D printing was performed. The accuracy of the reconstruction was checked by comparative measurements with an electronic vernier caliper of the diameters of the elements of the brachial plexus in identical places in preparations and three-dimensional models. The data obtained were entered into the MS Excel 12.0 program and the analysis of the generated database was carried out using the Statistica for Windows 12.0 0 program. Results and discussion. The developed 3D printing technique made it possible to reproduce the most accurate models of the brachial plexus with all elements (5 spinal nerves, 3 trunks, 6 divisions, 3 bundles and 15 nerves) in full size. A comparative qualitative analysis has shown that the created complete three-dimensional models have a high structural correspondence, improve depth perception, and emphasize spatial relationships. Quantitative analysis did not reveal significant differences in the diameters of the brachial plexus elements in the initial preparations and threedimensional models. The developed method and 3D-printed models make it possible to identify detailed features of the structure of the brachial plexus at the perineural level. Conclusions. Creating a complete set of three-dimensional models of all variants of the structure of the brachial plexus will allow you to operate in augmented reality and increase the efficiency of operations. The conducted research is also the basis for the subsequent manufacture of biocompatible and biodegradable transplants that will allow to repair complex nerve damage in the upper limb. |
