This paper reports six young male human cadaver femoral cortical bone 36 specimens in a direction transverse to the long axis of the bone and 36 specimnens in a direction parallel to the long axis of the bone compressive test. The results are that the elastic modulus, yield strength, ultunate strength and yield strain in a direction. parallel to the long axis of the bone is much greater than that in a transverse direction to the long axis of the bone. Their rates are 1.57,1.88,1.35 and 1. 48 respectively(P<0.0001).Statistical analysis, the energy absorption value in a direction parallel to the axis of the bone is significant higher than that in a direction transverse(P<0.05).This supported that human femoral cortical bone is anisotropic heterogeneous material. It supplies a significant data for the clinic.
