What is the Finite Elements Method (FEM)?

The technique used to predict the effectiveness of a brace on the trunk and skeleton of a patient is called the Finite Elements Method (FEM).

Above all, it provides an approximate solution of a problem.
Basically, the FEM allows a problem to be solved by dividing it into several small problems, and provides the results of the object’s dynamic behaviour: tension, deformation, pressure...

This method is widely used in the design and analysis of industrial products. For example, it is used in the medical field to simulate the insertion of implantable devices such as stents placed in veins or arteries

In our case, two Finite Element Models will be created: the FE model of the skeleton and the patient’s skin, and the FE model of the brace. Then, the two FE models will be superimposed in order to launch the simulation.

To obtain the FE model of the patient's skeleton, including the ribcage, spine and pelvis, this skeleton must be built in 3D. To do this, the front and profile calibrated X-rays of the patient are used.

The brace is created in Rodin4D Neo, and then converted into a FE model.

Once the FE models are superimposed, the simulation software can be launched.
