Dynamic consideration of expansive open-door laminoplasty by finite element analysis : about modeling method of cervical vertebra

Abstract

It increases in the symptom as cervical spondylosis every year. According to the report, more than 85% of more than 60 years of age has the cervical spondylosis. There are several remedies of the cervical spondylosis. The expansive open-door laminoplasty is one of several remedies of the cervical spondylosis. The expansive open-door laminoplasty progress is a part cutting, making slit, bending. It isn't being considered dynamically quantitatively of the operation procedure about the expansive open-door laminoplasty. Therefore, our goal of the research is the quantitative dynamic consideration of the operation procedure about the expansive open-door laminoplasty. One of our progress is to make the 3D model of the cervical vertebra from the computed tomographic, to make the mesh model, to do computer simulations of the expansive open-door laminoplasty. Now I cloud find to create the finite element model of cortical bone of the fifth cervical spine. But I cloud not find to create the finite element model of cancellous bone of the fifth cervical spine. So I’m going to create the easier model. I think I have to change to create ROI of cancellous bone and make the model cervical spine more smooth.
