Abstract: The elastic modulus and hardness of embedded and rewet trabecular bone lamellae of the proximal femur have been quantified in four males and four females by nanoindentation. The average elastic moduli ranged from 6.9 to 15.9 GPa and were found to be significantly different among individuals. Hardness correlated with elastic modulus and followed similar trends.
