The origin of the BraceSim project

Rodin SAS offers CPOs a complete CAD/CAM system with 3D scanners, rectification software and milling machines.
The company aims to provide innovative solutions based on the latest technologies, to help CPOs improve the quality of their devices.

This is why the CHU Sainte-Justine and the École Polytechnique de Montréal, as well as the American company Boston Brace and Rodin SAS launched a Research and Development project in 2009, with the aim of developing a simulator to evaluate the effectiveness of a brace in the treatment of idiopathic scoliosis.

Collaborating with the École Polytechnique in Montreal allows us to build on their 20 years experience in the Finite Element (FEM) simulation field applied to the treatment of scoliosis.

As a result of this project, 13 scientific articles have been published in leading scientific journals (Spine Deformity, Elsevier, Springer...).

Around ten clinical assessments have been conducted on more than 100 patients to prove the reliability of the simulation tool. Several types of braces such as the Boston, Caen’s, Providence... braces manufactured in a traditional way and in parallel, manufactured using CAD/CAM + simulation, have been tested.

The results of this research has proved the reliability of this tool and that it is possible to predict the effectiveness of a brace before it is manufactured, optimise the treatment success rate, and lighter braces which are equally effective.
Studies have evaluated the brace simulator’s precision to be 5 degrees for Cobb angles.

BraceSim is the result of this Research & Development project. It is the first simulation web platform for scoliosis braces, dedicated to CPOs.
