	abstract = {Young{\textquoteright}s\&nbsp;modulus\&nbsp;and\&nbsp;Poisson{\textquoteright}s\&nbsp;ratios\&nbsp;of\&nbsp;6 mm-sized cubes\&nbsp;of\&nbsp;equine\&nbsp;cortical\&nbsp;bone\&nbsp;were measured incompression\&nbsp;using a micromechanical loading device. Surface displacements were\&nbsp;determined\&nbsp;by\&nbsp;electronicspeckle\&nbsp;pattern-correlation\&nbsp;interferometry. This method allows for non-destructive testing\&nbsp;of\&nbsp;very small samples in water. Analyses\&nbsp;of\&nbsp;standard materials showed that the method is accurate and precise for determining both Young{\textquoteright}s\&nbsp;modulus\&nbsp;and\&nbsp;Poisson{\textquoteright}s\&nbsp;ratio. Material properties were\&nbsp;determined\&nbsp;concurrently in three orthogonal anatomic directions (axial, radial and transverse). Young{\textquoteright}s\&nbsp;modulus\&nbsp;values were found to beanisotropic\&nbsp;and consistent with values\&nbsp;of\&nbsp;equine\&nbsp;cortical\&nbsp;bone\&nbsp;reported in the literature.\&nbsp;Poisson{\textquoteright}s\&nbsp;ratios were also found to be\&nbsp;anisotropic, but lower than those previously reported.\&nbsp;Poisson{\textquoteright}s\&nbsp;ratios for the radial-transverse and transverse radial directions were 0.15 +/- 0.02, for the axial-transverse and axial-radial directions 0.19 +/- 0.04, and for the transverse-axial and radial-axial direction 0.09 +/- 0.02 (mean +/- SD). Cubes located only millimetres apart had significantly different elastic properties, showing that significant spatial variation occurs in equine\&nbsp;cortical\&nbsp;bone. (c) 2006 Elsevier Ltd.
