Hi, see some of my publications: Finite element analyses of human vertebral bodies embedded in polymethylmethalcrylate or loaded via the hyperelastic intervertebral disc models provide equivalent predictions of experimental strength, and
Strain changes on the cortical shell of vertebral bodies due to spine ageing: A parametric study using a finite element model evaluated by strain measurements.
It is always difficult to use other validated FE model, because different FE models were developed for different aims and as so some simplifications were made to meet the aim. It is always recommended to create your own subject-specific FE models
Congratulations Yongtao Lu for such a wonderful paper. I wanted to know ow much time did it take to develop and validate the model from the CT scan data. I know it will depend on person to person and based on the level of understanding , but I wanted to know an approximate time for this exercise because spending large amount of time in developing and validating the model will be a futile exercise and will be similar to reinventing the wheel.
Do u know how to model the cartilages and ligaments.
How do u segment the cortical and cancelous regions separately. ( I tried intensity based segmentation but it was a futile exercise as there was no clear demarcation of the cortical and cancelous region)
I think the model with cartilages and ligaments will not be in the scope of your research but it would be great if you could throw some light on the same.
We have make some model of vertebral bodies. Our experience is summarized in the following papers:
