In this research,shape-memory polyurethane foam was used to fabricate the expandable bone screw,which could be compressed before use,implanted in vivo through a minimally invasive procedure and actuated to expand to fit the fracture properly for fixation.Meanwhile,carbon nanotubes were incorporated to improve the mechanical properties of the foams.
