Abstract: A bone anchor element/inserter/system for inserting into a bone and/or fixing tissue to the bone. The bone anchor element has a proximal end, a proximal section, a distal section and a distal end, and the proximal section has on the outside a contoured. On the inside a continuous hollow space in the longitudinal direction there is a proximal opening and a distal opening. The distal section has in the longitudinal direction to the distal end a first transverse through-hole through the plate plane.

Abstract: Intramedullary fixation assemblies (4, 8) and intramedullary fixation devices (1, 24) can be used in orthopaedic surgery for the fixation of bone fractures. Also disclosed is an insertion device (30) for inserting an intramedullary fixation device, and a method of fixing a bone fracture. The fixation devices are preferably for addressing fractures of the distal radius, and are preferably styloid nails.
