Abstract— Drilling is an essential part of internal fixation in results explored by Bachus et al. [3] also showed that by the
orthopaedic and trauma surgery. The temperature rise during application of a larger force to the drill, both maximum cortical
bone drilling is an important index to the damage of bone. In this temperatures and their duration above 50 oC might be
study, an elastic-plastic dynamic finite element model is used to effectively reduced. Allan et al. [4] reported that the
simulate the process of a drill bit drilling through the bone.
Various initial temperatures of drill bit are investigated to temperature rise of drilling bone was related to the amount
