FEBio Finite Element Models of the Human Lumbar Spine

The purpose of this project is to develop open access finite element models of the human lumbar spine using open source software (FEBio Software Suite (https://febio.org/)). We are developing whole lumbar spine models (L1-5) and models of functional spine units (FSUs). Models are developed from CT image data segmented in our laboratory (https://mrl.sci.utah.edu/) and from porting models to FEBio that were first developed for commercial codes. This project is a collaboration between the Departments of Biomedical Engineering and Orthopaedics at the University of Utah, and we work closely with the FEBio development team.Please see the following reference for details about the models and cite this reference when using the models for further publications:Finley SM, Spina NT, Brodke DS, DeDen CA, Ellis BJ: FEBio finite element models of the human lumbar spine. Computer Methods in Biomechanics and Biomedical Engineering, 21(6): 444-452, 2018. <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=1450#pack_1985">Model 1 (49 y.o., F) </a> : Seven models are provided in this package: three whole L1-5 models (one for each meshing scheme), and four hybrid FSU models. </li> <li> <a href="https://simtk.org/frs?group_id=1450#pack_1986">Model 2 (59 y.o., F) </a> : Five models are provided in this package: one whole L1-5 hybrid model, and four hybrid FSU models. </li> </ul>

本项目的宗旨在于利用开源软件（FEBio软件套件（https://febio.org/））开发人类腰椎的开放获取有限元模型。我们正在构建整个腰椎（L1-5）模型以及功能脊椎单元（FSU）模型。这些模型基于我实验室（https://mrl.sci.utah.edu/）分割的CT图像数据，以及将最初为商业代码开发的模型移植至FEBio。该项目是犹他大学生物医学工程系与骨科之间的合作成果，我们与FEBio开发团队保持紧密合作。关于模型的详细信息，请参阅以下参考文献，并在进一步出版物中使用模型时引用此参考文献：Finley SM, Spina NT, Brodke DS, DeDen CA, Ellis BJ: FEBio有限元模型的人类腰椎。计算机生物力学与生物医学工程，21(6): 444-452, 2018。此外，本项目包含以下软件/数据包：
