KTH has published a new bone fixation technique called AdhFix in the high impact journal Advanced Functional Materials. The paper, which was authored by KTH’s Daniel Hutchinson and involved researchers from KTH and RISE in Gothenburg and hand surgeons working at Södersjukhuset hospital and Karolinska Institutet in Stockholm, describes how polymer composites based on thiol-ene coupling monomers and hydroxyapatite can be used together with metal screws to create strong, highly customizable, biocompatible and surgically feasible fixations for bone fractures. The approach, which involves a shapeable fixation patch built-up over the bone fracture with alternating layers or composite and fiber mesh, is similar to the strategy that will be used in the fixation patch in the BoneFix project. BoneFix, however will, not use metal screws, as a sophisticated primer system will be used instead to create strong adhesion between the composite and bone surface, resulting in a completely metal free fixation system.
