Illustration of trabeculae column and segmentation of the three parts. Each column was cut into three segments, using a low speed saw with a diamond cut-off wheel. The first part was used for the evaluation of water content, glycosaminoglycan (GAG) content and histology analysis, about 5% diameter of femoral head. The second part, which was first scanned by Micro-CT and then compressed to obtain mechanical properties which was 20% length of femoral head diameter.
