Temperature Rise Simulation During a Kirschner Pin Drilling in Bone

This study develops an analysis method which can be applied to simulating the temperature rise during bone drilling. A three-dimensional dynamic elastic-plastic finite element model is used to simulate the process of a Kirschner pin drilling through a bone. The results indicate that lowering the initial temperature of Kirschner pin can decrease the temperature rise as well as the size of the thermal affective zone. The results also show that a larger applied force can reduce the temperature rise effectively.
