Abstract
In this article, four variants of tibial lateral condyle split fracture stabilization (AO 41-B1.1) with two canulated cancellous screws were studied. The impact of a diameter and length of the thread on the distribution and values of the stress and displacement in the stabilization model was analyzed utilizing the finite element method. Geometric model was derived from CT imaging of 39 years-old female tibial bone. The geometric and numerical models of the individual variants of fracture stabilization were prepared in ANSYS Workbench Software. During the analysis, the Huber-Mises stress of each part of the models and the displacement between bone and split fragment were designated. An influence of the thread diameter on maximum values and distribution of the stress was observed while the thread length did not render any significant impact. For all analyzed variants, the displacement values and distribution were similar.
