Finite Element Analysis of Magnesium Alloy Based Bone Fixation Devices

Each year, there are over six million bone fractures in the U.S., over 30% of which require internal fixation devices to stabilize bone fragments during healing [1–2]. Currently, the gold standard materials for these devices are non-degradable titanium alloys. Unfortunately, these devices cause numerous complications and often require a secondary invasive removal surgery [3–4]. To circumvent these issues, resorbable polymeric devices have been developed, but their mechanical limitations render them inadequate for most load bearing applications [5–7].
