Objectives/Interrogation: The aim of the study is to develop a new way of planning and implementation of the corrective osteotomy of the radius, using the 3D modeling and individual templates, and also to analyze the proposed method in comparison with the classical method.

Methods: In the course of this study, 15 patients aged from 24 to 70 years were examined. The study was conducted on a Toshiba Aquilion 64 computer tomograph using specially developed protocols. Using a complex of 3D-adapted software, we performed individual 3D modeling and prototyping of anatomical models on MakerBot Replicator Z18 and Raise3D N2 DUAL 3D-printers. Individual templates were made on a 3D printer. For reference, in comparison, the second group of patients underwent classical measurements with the help of radiographs.

Results and Conclusions: The new protocol for planning and performing the corrective osteotomy of the radius, using 3D modeling and prototyping was developed. The analysis of the results of the planning and implementation of corrective osteotomy of the radius in 15 patients was carried out. The results showed that the application of the calculations obtained by drawing on radiographs, is not an accurate and reliable option in preoperative planning. Performing surgery with the use of the individual template totally eliminates subjective errors as well as the need to change the plan during operations.

After the surgical treatment, for control purposes, on the three-dimensional model the main angular parameters were once again calculated and compared with the planned preoperative calculations. The arrangements of osteotomized fragments and the plate were also taken into account.

The target, pre-planned spatial position of the fragments of the radial bone and the plate, corresponding to the preliminary calculations, was obtained in 94% of cases.

For the comparative analysis, we evaluated the archive results of 15 cases of planning the corrective osteotomy of the radius in patients with post-traumatic deformities using standard X-ray and radiographs of the radial bone in front and side projections. The spatial position of the proximal fragment of the radial bone and the location of the plate on the postoperative radiographs corresponded to preliminary calculations in 41 (79%) cases.

In addition, the comparative analysis of the calculations of 3D modeling and single-plane planning was conducted. The findings show that in 100% of cases the average difference in the measurement of the angular parameters was 6 ± 2 (p <0.05).
