CREATION OF COMPUTATIONAL MODELS OF CANCELLOUS BONE


Abstract eng:
The paper deals with a creation of computational model of cancellous bone. Cancellous bone is inner porous part of bones and it is of a very complex geometry. It is composed of special trabecular architecture and the trabeculae can be less than 1 mm in diameter. In most cases, cancellous bone is modeled as a “non-trabecular” solid body with an apparent Young’s modulus. The creation of a “trabecular” model of cancellous bone (which, in our opinion, is more appropriate) is quite difficult. MicroCT images are indispensable for this case as well as the software for their processing. Authors of this paper developed for this purpose a specialized software called STL Model Creator which works in Matlab platform. The software uses image processing methods in segmentation of cancellous bone images (thresholding). The paper introduces a method of creating of computational model and initial stress-strain analysis utilizing this model is presented as well.
