Repository of Thoracolumbar Spine Triangulated Meshes

Repository of Thoracolumbar Spine Triangulated Meshes:

• 42 stereolithography (stl) files (.stl extension) representing patient-specific thoracolumbar spine triangulated meshes ("42 Patient-Specific stl files.rar"), including point coordinates and triangulated mesh connectivity IDs. These stl files are reconstructed using sterEOS software (IRCCS, Milan), thanks to non-operated bi-planar images. Each stl file includes triangulated meshes of vertebras, pelvis, sacrum, and the femoral head. The stl files can be opened by many image viewers, 3D modelling, and CAD programs, like: Microsoft 3D Viewer (windows), and MeshLab (multiplatform). Data can be filtered, visualized, and downloaded using the data visualisation platform (https://thc.spineview.upf.edu/).
• 16807 stl files representing the thoracolumbar spine triangulated models ("stl.part01.rar" to "stl.part09.rar"), including point coordinates and triangulated mesh connectivity IDs. These stl files are sampled by combining the first 5 shape modes of the SSM, in which each shape mode is discretized into 7 Standard Deviations (SD): -3, -2, -1, 0, 1, 2, 3. Each stl file includes triangulated meshes of vertebras, pelvis, sacrum, and the femoral head. The stl files can be opened by many image viewers, 3D modelling, and CAD programs, like: Microsoft 3D Viewer (windows), and MeshLab (multiplatform). Data can be filtered, visualized, and downloaded using the data visualisation platform (https://thc.spineview.upf.edu/).
• An excel file "Descriptive_List.xlsx" reporting measured spinopelvic parameters for 42 patient-specific triangulated models, and virtual cohort 16807 triangulated models. Spinopelvic parameters are: Pelvic-Incidence (PI), Pelvic Tilt (PT), Sacral Slope (SS), Lumbar Lordosis (LL), LL-PI, Global Tilt (GT), Relative Pelvic Version (RPV), Relative Lumbar Lordosis (RLL), Lumbar Distribution Index (LDI), Relative Spinopelvic Alignment (RSA), T1 pelvic Angle (TPA), and scoliosis cobb angle. Global Alignment and Proportion (GAP) score is further measured as a complementary assessment. The Excel file has two sheets: sheet1 for 16807 virtual cohort, and sheet2 for 42 patient-specific models. Model ID in the excel file is correspondent to the model's name in both virtual cohort and patient-specific models. Model number in "Descriptive_List.xlsx" is correspondent to the same model number in 42 and 16807 FE input files, respectively (42 FE input files (DOI: 10.5281/zenodo.10994164), 16807 virtual FE input files (DOI: 10.5281/zenodo.8107354)).
