Shape Memory Alloy Applications in Bone Fixation: State of the Art

Abstract

Shape Memory Alloy (SMA) can transform its shape back to its original shape when subjected to a thermomechanical process. Applications of SMA in the bone fixation have been successful due the material’s ability to exhibit Shape Memory Effect (SME) as well as biocompatibility. A good design of bone fixation device made of SMA is capable of exerting a constant compressive force to the bone fracture while remains inert to the environment inside the host’s body. This study presents the application of SMA in bone fixation devices. These include SMA suturing devices, OSStaple, SMA patellar concentrator and SMA embracing fixator.
