对许多个体骨骼形状差异的详细分析有望揭示各种形态特征背后的力学意义。为了确定皮质骨区在横断面上的分布，检查了皮质骨区的中心质量分布(CMD)相对于整个横断面的CMD的相对位置。应用临床多层螺旋CT对90例人右侧股骨进行了扫描。对于每个股骨的9个横断面，我们测定了包括皮质骨和髓质区在内的整个区域的CMD为CMD-W，以及与CMD-C相同横断面的皮质骨区的CMD，并进行了比较。皮质的内侧和前部相对较厚，正好位于小粗隆下方。从骨干中心到远端，后皮质骨相对较厚。在整个骨干中，女性的CMD明显比男性更偏向内侧。这些结果表明，晚期皮质骨变薄的股骨倾向于在其内侧部分有皮质骨的集中。随着内侧弯曲度的增加，CMD-C距离骨干轴线越远。相反，骨干的侧弯越大，Cmd-C越接近骨干轴线。随着骨骼的数量随着年龄的增长而减少，可以进行自我调整，以便皮质骨的关键区域保持不变，以防止机械强度的下降。
A detailed analysis of differences in skeletal shape among many individuals is expected to reveal the mechanical significance behind various morphological features. To confirm the distribution of the cortical bone region in cross sections, the relative position of the central mass distribution (CMD) of the cortical bone region to the CMD of the entire cross section was examined. A total of 90 right human femoral skeletons were examined using clinical multi-slice computed tomography. For nine cross sections of each femur, we determined the CMD of the whole area, including both cortical bone and medullary areas, as CMD-W, and that of the cortical bone region in the same cross section as CMD-C, and they were compared. The medial and anterior portion of the cortex was relatively thick just below the lesser trochanter. The posterior cortical bone tended to be relatively thick in the region from the center to the distal part of the diaphysis. Females had a significantly more medially deviated CMD than males throughout the entire diaphysis. These results suggest that femurs with advanced cortical bone thinning tend to have a concentration of cortical bone in their medial portion. CMD-C was located farther from the diaphysis axis as the degree of medial bending increased. Conversely, the greater the lateral bending of the diaphysis, the closer CMD-C was to the diaphysis axis. As the amount of bone decreases with age, self-adjustment could occur so that the cortical bone's critical area remains to prevent a decrease in mechanical strength.
