Repository of Thoracolumbar Osteo-Ligamentous Spine Patient-Personalised FE Meshes

Repository of Thoracolumbar Osteo-Ligamentous Spine Patient-Personalised FE Meshes:

42 FE input files (.inp extension, Abaqus software, Simulia) representing patient-personalised thoracolumbar spine hexahedral meshes, including point coordinates, mesh connectivity IDs and element sets. Each input file is almost 99MB (totally 3.86GB), and it includes vertebras and IVDs hexahedral meshes; pelvis, sacrum, and the femoral head triangulated meshes; and ligaments.

An excel file: "Descriptive_List (42_P-S_FE_Models).xlsx" reporting measured spinopelvic parameters for 42 patient-personalised FE hexahedral meshes. The Excel file includes measured spinopelvic parameters (PI, PT, SS, LL, LL-PI, GT, RPV, RLL, LDI, RSA, TPA, and scoliosis cobb angle), GAP and IVD centric thickness for FE virtual cohort and patient-personalised FE meshes. Model ID in the excel file is correspondent to the model’s name.

One png file: "42_P-S.png" representing the first 10 patient-personalised thoracolumbar spine hexahedral models out of 42 FE models.

Notes:

1- Model number in "Descriptive_List (42_P-S_FE_Models).xlsx" is correspondent to the same model number in the 42 stereolithography (stl) files (.stl extension) representing the thoracolumbar spine triangulated meshes (DOI: 10.5281/zenodo.8108354; 42 Patient-Specific stl files.rar).

2-Models are reconstructed thanks to the Statistical Shape Modelling (SSM) and mesh morphing techniques, i.e., spine sagittal geometrical parameters could be measured by a clinical software like sterEOS or Surgimap, then, different shape modes of morphed-mesh SSM tool could be activated in order to obtain spine deformity. Then, pros and cons analyses between patient geometrical data and synthesized geometrical information could exploit FE patient-personalised thoracolumbar osteo-ligamentous spine models.

3- FE inp files can be opened by Abaqus 2019 and later. Any other FE software which supports .inp extension also can open the files.
