Abstract
A bone anchoring device includes an anchoring element with a shank to be anchored in a bone or a vertebra and a head. The anchoring device also includes a receiving portion with a first end and a second end opposite to the first end, a longitudinal axis passing through the two ends, a bore coaxial with the longitudinal axis, and a first region adjacent to the second end for receiving a section of said head. The anchoring device further includes an element which exerts pressure on said head to lock said head in the receiving portion. The receiving portion and the anchoring element are connected such that the longitudinal axis of the receiving portion and the shank axis have a fixed angle relative to each other. Additionally, the receiving portion and the shank are rotatable with respect to each other around the longitudinal axis and are locked in the rotational position when pressure is exerted on the head.
