Abstract

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.

利用有限元建模对 AO 44A1、44B1 和 44C1 骨折进行计算力学分析：评估螺钉、钢板和 Kirschner 钢丝固定。

背景：本研究旨在利用有限元分析创建 AO 44A1、44B1 和 44C1 骨折，以确定 Kirschner 线、髓内螺钉和钢板螺钉固定方法在骨折中的稳定性：方法：通过有限元分析，对 AO 44A1、44B1 和 44C1 骨折采用 Kirschner 钢丝、髓内螺钉和钢板螺钉固定方法的复位后行为进行分析，并从位移和应力方面进行比较：结果：在 AO 44A1 和 44B1 骨折中，髓内螺钉固定法的位移量最小，在 AO 44C1 骨折中，4 毫米 Kirschner 钢丝固定法的位移量最小。在 AO 44A1、44B1 和 44C1 骨折中，髓内螺钉固定系统的总位移量较低：根据有限元分析结果，在 AO 44A1 和 44B1 骨折中使用髓内螺钉固定的位移量最小，而在 AO 44C1 骨折中使用 4 毫米 Kirschner 钢丝固定的位移量最大。
