The whole process of brace production remains unchanged. In this study, the simulation software will not be used to influence the medical decision or the manufacture of the brace. In parallel with conventional production, anatomical transfer will be used in the deformed digital model of the trunk to simulate the effect of conventional brace on the spine. This modeling will be used to compare the correction of the conventional brace observed on the spine with EOS imaging system, with that simulated by the software.
