Özet

Background: The aim of this study was to create AO 44A1, 44B1, and 44C1 fractures using finite element analysis to determine the stability of Kirschner wire, intramedullary screw, and plate-screw fixation methods in fracture. Methods: Using finite element analysis, the postreduction behavior of AO 44A1, 44B1, and 44C1 fractures with Kirschner wire, intramedullary screw, and plate-screw fixation methods was analyzed and compared in terms of displacement and stress. Results: The lowest amount of displacement was provided with the intramedullary screw method in AO 44A1 and 44B1 fractures and with the 4-mm Kirschner wire method in AO 44C1 fractures. The total displacement of the intramedullary screw system used for fixation in AO 44A1, 44B1, and 44C1 fractures was lower. Conclusions: According to finite element analysis results, the lowest amount of displacement was obtained with intramedullary screw fixation in AO 44A1 and 44B1 fractures, and 4-mm Kirschner wire fixation was achieved in AO 44C1 fractures.
