Bone Abstracts

Objective: The aim of this study is to compare the bone health index (BHI) for healthy Swiss children born in 1955 with healthy Swiss children born a generation later.Method: BHI is derived from the cortical thickness in the three middle metacarpals. It is determined with the BoneXpert medical device, which automatically analyses a standard bone age hand radiograph. The measurement result is independent of the sharpness of the image. The image data are f...

Objective: The BoneXpert method for automated bone age determination from hand X-rays also determines the cortical thickness T and the bone width W in the three middle metacarpals. From these, the method derives the cortical area A=π W T (1 – T/W), the metacarpal index MCI =A/(WW) and the Bone Health Index. Recently, the method has been extended down to new-borns, and the aim of this study is to report reference curves for these bone measures.M...
