3D-model generation. All scans were segmented (a) and the subsequent segmentations were converted in 3D bone models (b) in Mimics software. The following settings were used: interpolation method ‘contour’, preferred ‘continuity’, shell reduction to 1, no matrix reduction applied and smoothing factor 0.3 using 2 iterations and exported as binary stereolithography (STL) file. Radius (yellow) and ulna (purple)
