Abstract
A bone anchoring device includes a receiving part with a recess for receiving a rod and a flexible head receiving portion for pivotably holding a head of a bone anchoring element, a pressure member configured to exert pressure on the head when the head is held in the head receiving portion, and a clamping ring positionable around the head receiving portion and movable from a first position where the head is pivotable relative to the receiving part, to a second position where the clamping ring exerts a radial force on the head receiving portion to lock the head relative to the receiving part. When the clamping ring is at the first position, the clamping ring abuts the receiving part to restrict upward movement, while a surface of the clamping ring that faces upwards is exposed for engaging an instrument to move the clamping ring to the second position.
