Determining bone mineral density of the strenum: comparison of different methods

The research results provided data on sternum regional density determined by direct measuring. The standard methods to determine bone mineral density in vitro on the sternum model were compared, and the obtained correlation coefficients between single methods show that all the methods may be reliably used in biomechanical studies on cadaveric samples. To determine mineral density in vivo it is necessary to use the method of quantitative computed tomography (QCT), for this method does not only show the density distribution within the cross-section, but also the geometry of the cross-section, which may be used in calculating the moments of inertia, the main parameters used to determine the bearing capacity of a certain construction element.
