Since the nineteenth century, orthopaedic surgeons have been using metal implants to immobilize fractured bone segments or hold implants in place. However, the titanium or steel screws can cause later problems, including infection, and sometimes need to be removed, resulting in another operation. Now, biomechanical engineers from Graz University of Technology (TU Graz) have teamed up with medical startup Surgebright to develop surgical screws made from human bone. The screws, dubbed ‘Shark Screws’ were originally developed in 2013 by orthopaedist Klaus Pastl, but this is the first time they have been developed and produced for multiple applications.
