The bone shape is supposed to have an optimal structure against the loads acting on it. The trabecular system, which has a complicated mesh-like structure and a certain pattern, is observed inside the bone. The trabecular system is also supposed to be constructed against the load. So, it is considered that unknown parameters about applied loads can be estimated from the factors of trabecular system. In this research we analyze human heel which X-ray picture has little noise by muscles. By comparing trabecular information aquired by image processing with the principal stress distribution obtained by finite element analysis, we estimate the loads acting on the foot. Moreover, we examine difference of respective forces among normal, hemiplegia, and quadriplegia patients.
