A bone is changing to the optimal shape and trabecula structure in response to the mechanical environment. This paper was investigated to simulate the optimal trabecula distribution in the femur using the growth-strain method applying FEM. We replaced the strain-energy density generated in the femur with the Young's modulus when the external load was added to the femoral head. As a result, the distribution of the femoral trabecula was simulated using the distribution of the Young's modulus. The femoral trabecula where the strain-energy density was large was generated in the large bone density.
