Abstract

A bone anchoring device includes an anchoring element having a shaft and a head, a receiving part having a coaxial bore and a seat for receiving the head, a pressure element configured to be movable within the bore, and a preload element being positionable between the head and the pressure element. When the head is inserted in the receiving part, the head is pivotable with respect to the receiving part, and can be locked at an angle relative to the receiving part by the pressure element. The pressure element can assume a position relative to the receiving part where the pressure element and the preload element are in direct contact, and where the pressure element exerts a force onto the head via the preload element to maintain one of a plurality of releasable angular positions between the head and the receiving part by friction before locking the head.
