Computational mechanical analysis of AO 44 A1, B1 and C1 fracture with Finite Element: Evaluation of screw, plate and k-wire fixation

Abstract

Abstract Background: The aim of this study was to create AO 44 A1, B1 and C1 fractures using finite element analysis (FEA), to determine the stability of k-wire, intramedullary screw (IS) and plate-screw (PS) fixation methods in fracture Methods: Using FEA the post-reduction behaviour of AO 44 A1, B1 and C1 fractures with k-wire, IS and PS fixation methods was analysed and compared in terms of displacement and stress. Results: The lowest amount of displacement was provided with the IS method in AO 44 A1 and B1. It was observed in the detection of 4 mm k-wire in AO 44 C1. The total displacement of the IS system used for fixation in AO 44 A1, B1 and C1 fractures was lower Conclusions: According to FEA results, the lowest amount of displacement was obtained with IS in AO 44 A1 and B1, while 4 mm K-wire fixation was achieved in AO 44 C1 fractures.
