It is well known that bone has a capability to adapt to usual mechanical environment and to reconstruct functionally its structure and geometry. This phenomenon is called as the adaptive bone remodeling. One of the most important mechanical factor of the remodeling is the stress. To generate the bone remodeling, the stress should remain to stimulate the osteocyte in the relative long period. Thus stress will be a kind of residual stress. To verify this assumption, it is a great significance to measure the residual stress in bone tissue. This paper describes a method to measure the residual stress in rabbit's tibia using the characteristic X-ray diffraction. Bone powder with below 45μm diameter was used as non-strained specimen. As a result, it is proved that the residual stress distributes in rabbits' tibia. The residual stress will occur to not macroscopic bone structure but microscopic bone tissue.
