Data for the paper: "Patient-specific finite element models of posterior pedicle screw fixation: effect of screw's size and geometry"

Data used in the paper: "Patient-specific finite element models of posterior pedicle screw fixation: effect of screw's size and geometry"Sensale, Vendeuvre, Schilling, Grupp, Rochette and Dall'Ara published in Frontiers Bioengineering and Biotechnology<br>We share here the results and one example of FE models for the implanted vertebrae.<br>Short description of the files included:<br>-) the results of the paper are reported in "Results_file.xlsx". In this file, there are different sheets:.NumElements_CompTime - this contains the number of elements and computational time to solve the FE models, reported in Table 2 and 3;<br>.MeshConvergenceStudy - this contains the results of the Mesh convergence study reported in Figure 3.<br>.Sensitivity Deflection - Stress AND Sensitivity Strain - these contain the results of the sensitivity analysis reported in Table 4, 5 and 6;.Correlation - this contains the results of the correlation analysis reported in Figure 6;<br><br>-) In the "Frequency_plot_files" folder, the result files for the frequency plots reported in Figure 7 are reported:.MinStrainMeshPoints(...).txt - these files contains the values of minimum principal strain used in the frequency plots in Figure 7.<br><br>-) The "Example_Model" folder contains an example of the models used in the sensitivity analysis for Patient #3 with simplified pedicle screw with diamter D6.5mm and length L45mm<br>The folder contains:- the Ansys workbench 2020R2 project file corresponding to the model in the name of the folder;- the corresponding geometry SpaceClaim file;- the Ansys cdb mesh file exported from Bonemat;- the calibration xml file used in Bonemat;- the Ansys apdl command snippet used in Mechanical to build an heterogeneous model of the bone.<br>In case the reader is interested in the whole database they should contact Dr Enrico Dall'Ara ([e-mail]).
