To obtain basic data about the holding power of a 4.5 mm AO/ASIF cortex screw in cortical bone in relation to bone mineral as expressed by densitometric methods, uniaxial pull-out tests were performed on 14 human cadaver femurs. The mechanical parameters were correlated with bone mineral which was assessed by quantitative computed tomography (QCT) and dual energy X-ray absorptiometry (DXA). High correlations were found between the QCT mass, the DXA density and content values and the holding power of the screw. The QCT density values, expressing the physical density of the bone, did not correlate similarly well.
为获取有关4.5毫米AO/ASIF皮质骨螺钉在皮质骨中的把持力与骨密度测量法所表示的骨矿物质之间的基础数据，对14具人类尸体股骨进行了单轴拔出试验。将力学参数与通过定量计算机断层扫描（QCT）和双能X线吸收法（DXA）评估的骨矿物质进行关联。发现QCT质量、DXA密度和含量值与螺钉的把持力之间存在高度相关性。表示骨物理密度的QCT密度值的相关性则没那么好。
