In a study based on a tibia bone fractured in the diaphyseal region, a Circular External Fixator (CEF) was implanted in this region and its effects were investigated during gait. The CEF mounted on the adult human tibial fracture line is constructed from four standard rings. The six most effective states were selected in terms of force and moment values on the tibia during the human gait cycle. According to the results, it was determined that the stresses are at a maximum in the Kirschner wires in the lower segment. Hence, it was ascertained that the wire and bone junction regions are important and that the geometric and mechanical properties of the wires close to the fracture line should be improved.
