Abstract
A bone anchoring device includes an anchoring element having a shaft and a head; a receiving part having a top end, a bottom end, a rod recess, a coaxial bore, and a seat; and a pressure element that is movable within the bore. The head is pivotable with respect to the receiving part and can be fixed at an angle by exerting pressure via the pressure element onto the head. The pressure element has an outer wall portion having a recess or a projection. The receiving part has an inner wall portion having a recess or a projection that cooperates with the recess or projection of the pressure element. The pressure element is configured to assume a first position within the receiving part in which the recess and the projection interact to allow the pressure element to exert a preload onto the head and the head is prevented from freely pivoting but is not locked.
