Abstract
It has been shown in precise studies that positioning of the lower limb during dual-energy X-ray absorptiometry (DXA) scans influences the outcome of areal bone mineral density (aBMD). Recently, DXA image data of the proximal femur has been used to calculate structural geometrical variables. These cross-sectional structural geometrical variables are useful in providing information on the strength and structural integrity of the proximal femur. However, because of the spatial dependence of these structural geometrical variables, positioning of the lower limb during DXA scans becomes more crucial.
This project is aimed at investigating the effects of rotation (i.e. positioning) on the lower limb and its corresponding effects on the cross-sectional structural geometry outcome. Variables that will be investigated are areal bone mineral density (aBMD), buckling ratio (BR), cross-sectional area (CSA), cross-sectional moment of inertia (CSMI), cortical thickness (Ct) and section modulus (Z).
