Three-dimensional printed models of the distal radius fractures were created using 2-dimensional computed tomography scan files in Digital Imaging and Communication in Medicine format, processed with the 3-dimensional Slicer software, and segmented, creating a 3-dimensional printed model in Standard Triangle Language format. Threedimensional models were printed using fused deposition modeling (FDM) type 3D printer Zortrax M200Plus using polylactic acid material on a scale of 1 : 1. Twenty observers were invited into the study.\n\nResults: Intra- and inter-observer reliability was analyzed using Fleiss\u2019 kappa statistics. Overall kappa values for both groups in interobserver agreement range from 0.113 to 0.283 and in intra-observer agreement from 0.25 to 0.545. Generally, inter-observer agreement increased with additional 3-dimensional printed models from slight to fair, and intra-observer agreement increased from fair to moderate. Surgeons\u2019 opinions about 3-dimensional printed models with Likert scale-type questions show positive overall results ranging from 8.3\u00b1 2.1 to 8.6 \u00b1 1.4.\n\nConclusion: This study has shown that the inter- and intra-observer agreement with the addition of a 3-dimensional printed model for the evaluation of the distal radius fractures of Association For Osteo synth esis\/ Ortho pedic Trauma Association C type for classification, fractures morphology, and preoperative planning tends to increase; however, improvements for an inter-observer agreement remain fair.\n\nLevel of Evidence: Level III Diagnostic Study\n\nCite this article as: Grin\u010duk A, Makulavi\u010dius A, Porvaneckas N, Ryli\u0161kis S, \u0160atkauskas I, Uvarovas V.
