Biodegradable Mg-Based Alloys for Orthopaedic Implants in Biomedical Applications

Abstract

Orthopaedic implants, traditionally made from non-degradable materials like titanium and cobalt-chromium alloys, are used to replace lost bone or soft tissue from various causes, including trauma and disease. These traditional implants often necessitate a second surgery for removal. Biodegradable implants, on the other hands, offer a significant advantage by eliminating the need for additional surgery, as they naturally degrade within the body over time. In this article, the properties, biodegradation, bone-regeneration, and applications of biodegradable Mg-based alloys for orthopaedic implants in biomedical applications are explored. It also discusses the challenges and prospects of biodegradable Mg-based alloys as orthopaedic implants.
