Abstract:
A bone anchoring device includes an anchoring element having a shaft and a head; a receiving part for receiving the head and a rod, the receiving part being formed in one piece and having a top end and a bottom end, a bore extending from the top end to the bottom end, an inner wall defined by the bore, a substantially U-shaped channel adjacent to the top end for receiving the rod and a seat adjacent to the bottom end for accommodating the head; a pressure element; and a spring element having a spring force. The anchoring element is inserted from the top end and is pivotable with respect to the receiving part. The pressure element is movable in the bore so as to be able to fix the anchoring element at an angle with respect to the receiving part by exerting pressure onto the head. The spring element acts between the pressure element and the receiving part and allows the pressure element to be introduced from the top end but withstands against removal of the pressure element through the top end.
