"Implementation of new materials into orthopedic implants" 

We will discuss the translation of a diverse set of new material technologies into orthopedic implants. In all the applications, the implementation of the new materials was accelerated by basic research leading to a new fundamental understanding of the relationship between processing, structure, and mechanical properties of the constituent materials. The examples span implants and new materials that have been successfully used in nearly ten thousand patients, to materials yet to be cleared in a device by the FDA. The topics to be overviewed include: The development and understanding of deployable shape memory polymers to mitigate damage when reattaching soft tissue to bone. A fundamental breakthrough on the processing and machinability of shape memory alloys to enable a paradigm shift in the success of large bone intramedullary fusion devices. A new approach to the formation of an interconnected surface porosity in a high strength polymer that results in the first ever FDA clearance and clinical success of an all polymer spinal fusion cage with porosity. Finally, a 3D printed, bio-mimetic elastomer is shown to have early promise as a reliable and long-term soft tissue replacement or scaffold.
