title: [The effect of rehydration on the elasticity modulus and strength of lyophilised and irradiated femur bone in the human].
abstract: The influence of rehydration on elasticity modulus and strength of lyophilized and irradiated cortical bone of human femur was studied by means of balance rheometer. The measurements were taken in 20(C and at sample deformation frequency of 12.5 Hz. The bone samples were taken from 40 individuals aged 35-45 who died suddenly. It was found, that after 24 hours rehydration the elasticity modulus of lyophilized and irradiated cortical bone decreased about 11% and strength increased about 18%. The greatest changes of elasticity modulus were observed during first 10 hours of rehydration. Strong negative correlation (r = -0.8, p < 0.001) between changes of elasticity modulus and degree of the bone rehydration was confirmed.
