The Screw That Dissolves

Where bones fracture, surgeons often have to join the fragments with implants. Magnesium orthopaedic screws, which over time dissolve in the body, spare patients another operation after healing is completed and reduce the risk of infection. What happens inside the body during this process, though, is still largely unknown. To develop optimized alloys and orthopaedic screws with functionalized surfaces, Empa researchers are now investigating magnesium corrosion.
