9 | Biomaterials

Module 9 | Biomaterials Develop a comprehensive understanding of biomaterials used in orthopaedic surgery with this module covering the mechanical principles of materials science and the properties of commonly used implant materials. These concepts form a cornerstone of orthopaedic basic science and are frequently examined in the FRCS Part 1 Basic Science examination. You’ll begin by exploring the fundamental concepts of biomaterials, including key definitions, stress and strain, material properties, fatigue failure, and viscoelastic behaviour. The module then examines the structure, manufacture, and characteristics of orthopaedic metals before progressing to non-metallic biomaterials, including bone cement, polyethylene, and ceramics. Throughout the module, you’ll develop an understanding of how material properties influence implant design, performance, longevity, and clinical application. Topics Covered Biomaterial Concepts 1.
