Abstract
The use of volar plaque is indicated for the treatment of distal radius fractures. In order to protect the extensor tendons from the opposite side of the plate, the objective of this study was to evaluate the influence of two screw lengths (unicortical and bicortical) on the fixation of the plate through the Finite Element Method. Computed tomography images of the synthetic bone were obtained with the complete assembly, generating DICOM files. These files were converted to STL format using the InVesalius ™ program. Subsequently, with the use of the program Rhinoceros ™ 3D was realized the three-dimensional modeling of the BioCads. These three-dimensional models were exported to the Simlab ™ program, where meshes and nodes were defined. The analysis of the finite elements showed that the unicortical and bicortical fixations did not result in any region of critical stress concentration, so that both are indicated for the stabilization of the radius fractures.
