An Outlook on Magnesium-Based Biodegradable Implants

[Extract] In this ageing population, the use of implants for repair of bone fractures is increasing rapidly. Mini-implants such as plates and screws are often used for bone fracture healing. Currently non-degradable implants made of metallic materials such as stainless steel, titanium alloys or chromium-cobalt alloys are commonly used. However, the long-term exposure of these non-degradable implants greatly increases the risk of complications such as foreign body reactions and inflammation due to the release of metal ions or particles as a result of corrosion/wear. This necessitates a secondary surgical process to remove the implant after healing of the tissues. In fact, repeat surgery is a risk and also increases the costs to both the patient and the health care system
