Analysis of plate-screw fixation by finite element method in transverse fractures of the tibia diaphysis
Journal Title: Ege Tıp Dergisi - Year 2016, Vol 55, Issue 3
Abstract
Aim: Using the Finite Element Method, it was aimed to select the most appropriate implant for a patient with a transverse tibia diaphysis fracture and to determine the effect of sudden temperature changes on the selected implant. Materials and Methods: After separating the diaphyseal area into transverse pieces at 1 cm regular intervals, the anterior and lateral views of the cross-sections enabled the generation of a computer model of tubular bone with 3 cortices. An 8-hole plate with 8 screws was placed over the lateral cortex of the tibia on the model. After creating a transverse fracture in the exact centre of the plate, the whole model with bone-plate-screw was converted into a mathematical model (mesh). The results of the analysis were evaluated using the finite elements method. Results: The tensile values were found to be greatest on the 2nd holes and screws from the proximal and distal of the fracture line. In the evaluation of temperature changes, the plate-screw tensile values were determined as normal in a cold environment but were seen to be high compared to those of a hot environment. Conclusion: By finding the tensile values on plate-screw-bone with this method preoperatively, the most appropriate plate-screw to be used on the patient can be determined. In addition, as tensile force on the plate-screw increased with transfer from a hot environment to a cold one, it could be said that fractures are more likely to occur in a cold environment.
