Jd. Currey et al., THE EFFECTS OF AGING AND CHANGES IN MINERAL-CONTENT IN DEGRADING THE TOUGHNESS OF HUMAN FEMORA, Journal of biomechanics, 29(2), 1996, pp. 257-260
Static toughness and impact strength of human cortical bone decline wi
th age. This decline is strongly associated with an increase in the as
h content of the bones but other factors, associated with age, are pro
bably also responsible for the degradation of the bones' mechanical pr
operties.
