This study aims to develop an image processing system for the estimation of trabecular strength and to investigate the relationship between the loads and the trabeculae in the femoral head. The trabecular system is a useful source of knowledge for the mechanical environment of bone which is important in using orthopedic treatment. In this paper, the distribution of principal stress obtained by the finite-element model based on Pauwels' theory is compared with that of trabecular strength estimated using the image processing technique. It is found that the result of finite-element method is similar to the configuration of trabeculae in both magnitude and direction. This result shows that unknown applied loads to bone may be estimated using the inverse finite-element method.
