To investigate activities of bone cells and mechanism of micro fracture in cancellous bone in detail, stress analysis considering structure of trabecular bone is necessary. Biological apatite (BAp) crystallite orientation is also related to micro stress in trabecular bone. So that, stress analysis of trabecular bone reflected BAp crystallite orientation and its software development is required for osteoporosis diagnosis and biomechanical study of bone. In our previous study, we proposed the multi-scale stress analysis of trabecular bone by the homogenization method bridging nano-micro-macro scales and the mesh superposition method to evaluate the micro stress of the trabecular bone. Furthermore, we have also been developing the unified system implemented the technique for the multi-scale analysis for practical application. In this paper, we present especially the modeling technique of the analysis system and its efficiency is discussed.
