Biomechanical modeling in determining the fixation strength of various implants in the treatment of type C3 intra-articular distal radius fracture (biomechanical study)

I.M. Zazirnyi, А.V. Vasylenko


The article presents the results of the biomechanical modeling of axial loads on the “implant-bone” system in type C3 distal radius fracture. The analysis of stress and strains arising during the formation of fragments of the distal radius and implant at the time of rehabilitation has been carried out. The aim of the study was to improve the treatment outcomes in patients with unstable, severe, intra-articular type 23-C3 distal radius fractures. The task of the study was to determine the dependence of the value of fragment displacement on the magnitude of the applied load when fixing with different fixing systems; to evaluate the stabilization properties of different types of fixation (wires 2.0 mm, plates without angular stability, plates with angular stability and fixed angles and plates with polyaxial angular stability) when modeling type C3 distal radius fracture, to determine the optimal type of fixation for type C3 distal radius fracture.
