Abstract

Bovine cortical bone is selectively demineralized by timed immersion in supersaturated (ethylenedinitrilo)-tetraacetic acid. The resulting demineralized and mineralized tissues are characterized using a scanning acoustic microscope with a 50 MHz transducer and three histological protocols. The sonic wave velocities and elastic moduli of the mineralized tissue and collagen are found to be 3.65 +or- 0.12 km/s and 1.49 +or- 0.06 km/s and 27.2 +or- 2.5 GPa and 2.95 +or- 0.26 GPa, respectively. The results of this preliminary study indicate that scanning acoustic microscopy combined with histological evaluation has promise as a means of assessing acoustic and material properties of cortical bone on a site-specific basis.
