1. A bone anchoring device for anchoring and fixing vertebrae, with a fork head having a U-shaped cutout in a side view for a correction element,
and a bone anchoring element having a proximal end in the axial direction, such that a distal direction and a proximal direction are also defined, wherein the bone anchoring element has a spherical head at the proximal end area and the bone anchoring element can be pivoted polyaxially with respect to the fork head, and the bone anchoring element can be mounted with the fork head, wherein the bone anchoring element has a substantially cylindrical core, and in that the core at the proximal area enlarges in diameter at least in sections from distal to proximal, and in that two wings extend laterally from the core and the wings have a distal wing orientation and a proximal wing orientation different from the distal wing orientation, and in that the wings form helically between these wing orientations, and in that the bone anchoring element is not configured to be screwed into the bone but to be hammered in.
