On each section hardness values were not constant. Therefore it was concluded that it is extremely difficut to suggest any mathematical formulae or hypothesis representing the law of anisotropy of spongeous bone. In order to achieve constitutive equations explaining biomechanical behavior, it is necessary to run several mechanical and microstructural experiments on the various sections.}, number={1}, publisher={Turkish Association of Orthopaedics and Traumatology}
