Many experts<br \/>\nin orthopedic surgery recommend the use of a Delta external fixator for type III Pilon fracture treatment. This device can promote<br \/>\nimmediate healing of fractured bone, minimizing the rate of complications as well as allowing early mobilization. The characteristics<br \/>\nof different types of the Delta frame have not been demonstrated yet. By using the finite element method, this study was<br \/>\nconducted to determine the biomechanical characteristics of six different configurations (Model 1 until Model 6). CT images<br \/>\nfrom the lower limb of a healthy human were used to reconstruct three-dimensional models of foot and ankle bones. All bones<br \/>\nwere assigned with isotropic material properties and the cartilages were assigned to exhibit hyperelasticity. A linear link was used<br \/>\nto simulate 37 ligaments at the ankle joint. Axial loads of 70 and 350 N were applied at the proximal tibia to simulate the stance<br \/>\nand swing phase. The metatarsals and calcaneus were fixed distally in order to prevent rigid body motion. A synthetic ankle bone<br \/>\nwas used to validate the finite element model. The simulated results showed that Delta3 produced the highest relative<br \/>\nmicromovement (0.09 mm, 7 \u03bcm) during the stance and swing phase, respectively. The highest equivalent von Mises stress<br \/>\nwas found at the calcaneus pin of the Delta4 (423.2 MPa) as compared to others. In conclusion, Delta1 external fixator was the<br \/>\nmost favorable option for type III Pilon fracture treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Download the article here Abstract Pilon fractures can be caused by high-energy vertical forces which may result in long-term patient immobilization.
