Prediction of 3D Effect of Brace in Idiopathic Scoliosis Treatment Using EOS Imaging System and Anatomic Transfer.

Study Overview
=================
Brief Summary
-----------------
In this study, the accuracy of a new numerical method is evaluated for predicting the 3D effect of brace on idiopathic scoliosis. This method results from the combination of several innovative technologies: the EOS imaging system and the anatomical transfer developed by Anatoscope. This is an essential step in validating a digital tool that can be used in routine clinical practice.

Detailed Description
-----------------
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. EOS Tranfert study is a observationnal, prospective, monocentric, unrandomized and controlled study. This research doesn't modify care of the patient
