Optimisation of brace treatment with numerical modelling

Scoliosis is a spinal deformation which can be cured by a brace treatment. In this study, we focus on the most important group of scoliotic patients called ‘idiopathique’ (unknown origin). Most of the time, braces used the mechanical principle of three points flexion (Rigo et al. 2006). This strategy is not always efficient for stopping the spinal deformation evolution (Bullmann et al. 2004). The aim of this study is to optimise this rigid treatment. Our hypothesis is that surface loading in a specific place can correct scoliosis deformation. We can evaluate this theory by a squelettal model including disc. On one hand, it requires numerical modelling and on the other hand an exploitation by testing surface loading in order to explore new strategy.
