We measured bone density in various parts of the femur by using single energy quantitative computed tomography. In the cadaver studies we found significant correlations between the trabecular and cortical bone density and the structural strength of the femur in bending and rotational loading. This was observed in parts of the femur distant from the fracture site in the femoral neck. Good reproducibility of the density measurements was obtained at the condylar level, a site easily accessible for clinical measurements. In a clinical study, we could record post-traumatic osteoporotic changes at 5% precision level.
我们使用单能定量计算机断层扫描测量了股骨各部位的骨密度。在尸体研究中，我们发现小梁骨和皮质骨密度与股骨在弯曲和旋转负荷下的结构强度之间存在显著相关性。在股骨颈骨折部位较远的股骨部分观察到了这种情况。在髁突水平获得了良好的密度测量重复性，髁突是一个便于临床测量的部位。在一项临床研究中，我们能够以5%的精度记录创伤后骨质疏松性变化。
