Effect of cryo-induced microcracks on microindentation of hydrated cortical bone tissue

Yin, Ling; Venkatesan, Sudharshan; Webb, Daryl; Kalyanasundaram, Shankar; Qin, Qing Hua


Microcracks accumulate in cortical bone tissue as a consequence of everyday cyclic loading. However, it remains unclear to what extent microdamage accumulation contributes to an increase in fracture risk. A cryo-preparation technique was applied to induce microcracks in cortical bone tissue. Microcracks with lengths up to approximately 20 μm, which were initiated mainly on the boundaries of haversian canals, were observed with cryo-scanning electron microscopy. A microindentation technique was...[Show more]
