Abstract

The use of external fixation devices in orthopedic surgery is very common in open tibial fractures. There are several hypotheses of the structure configuration: uniplanar-unilateral; uniplanar-bilateral; biplanar and multiplanar. The stability on the focus of the fracture is also related to the type of configuration of the external fixators. The unilateral-uniplanar configuration was considered in this study. A simplified finite element model for the tibia and external fixator was developed in order to determine the stiffness in the focus of the fracture. A genetic algorithm was defined to minimize the displacement of the fracture focus (objective function), varying the positions of the mechanical components of the external fixator. Different types of loading were studied and the obtained results are presented and discussed.
