femur biomechanical measurement bone stiffness femur stiffness 2013-06-27T18:48:55Z A calculated measurement of the rigidity of the femur, that is, the extent to which it resists deformation in response to an applied force, taken as the initial, i.e. the maximum, slope of the load-displacement curve. The femur is the major bone in the upper portion of the hindlimb of quadrupeds or the lower limb of bipeds. Bone is the hard, rigid form of connective tissue constituting most of the skeleton of vertebrates and composed chiefly of calcium salts.
