Human-robot interaction for 3D telemanipulated fracture reduction

Today, femoral shaft fractures are usually stabilized by means of intramedullary nails. This video presents the development of a telemanipulator system, which, by supporting the fracture reduction process, aims at achieving reliable operation results with high reduction accuracies. First, we present a system using 2D X-ray images as base information for the surgeon to guide the reduction. We show the advantages but also the limitations of this approach, which finally led to the development of a telemanipulator system that is based on 3D imaging data instead.
