Trabecular and cortical volume of interests and experimental setup for three-point bending tests. (A) Representative 3D reconstructed tibia showing the total tibial length (L). The trabecular VOI started at ~0.35 mm distal to the growth plate and extended for 12% of the overall bone length (L). The VOI for cortical bone was centered at the tibial mid-diaphysis and extended proximally and distally for 5% of the tibial length (L). Volumes of interest including only trabecular and cortical bone were semi-automatically segmented using an in-house algorithm. (B) I-Experimental setup for the three-point bending tests. A distance of 50% of the total tibial length was fixed between the supports, while the remaining 50% was distributed equally between the external sides of the supports. II- Representative image of the fractured tibia after the bending test.
