N2 - Material selection for an implant is one of the elements that must be considered in the healing process of a broken bone. Complications such as implant loosening, malunion, non-union and deformity may happen if wrong material of implant is used. Therefore, this study presents a finite element analysis on external fixator used in treating Type III pilon fracture to simulate the effect of different materials used. The main aim of the study is to evaluate the use of titanium alloy and stainless steel for delta external fixator construct and its effects from biomechanical point of view. Von Mises stress, displacement and micromovement are the concerned parameters in evaluating and describing the stability and stiffness of the construct, and how well does it support the bone healing process. Three-dimensional model of foot and ankle bones were reconstructed using Mimics software and tested according to physiological condition. The finding shows that stainless steel external fixator experienced less stress at the pin-bone interface of tibia bone as compared with titanium alloy construct. The use of stainless steel material also helps in promoting bone healing process as there are micromovement observed at the fracture fragments. Therefore, in terms of biomechanical aspect, it is suggested that stainless steel material is the best option for the external fixator in treating type III pilon fracture.
