EN This article is focused on using the Finite Element Analysis (FEA) for assessing the mechanical strength of a wrist-hand orthosis manufactured by Fused Deposition Modelling (FDM) for a patient suffering from a fracture that needs stabilization. The finite element analysis has been performed by simulating a three-point bending test, which is the most relevant method for evaluating the strength of such medical devices. The numerical results have been used for examining the distribution of the von Mises equivalent stress for different bending loads, as well as for determining the critical load for which the maximum value of this stress reaches the yield strength of the base material. After validating its design by FEA, the wrist-hand orthosis has been manufactured by Fused Deposition Modelling.
