Abstract
A bone anchoring device includes a receiving part for coupling a rod to a bone anchoring element, the receiving part having a first end, a second end, a recess at the first end for receiving the rod, and a compressible head receiving portion at the second end for accommodating a head of the bone anchoring element, a pressure member positionable in the receiving part to exert pressure on the head, and a clamping ring positionable around the head receiving portion and movable towards the first end of the receiving part to a locking position where the clamping ring exerts force on and compresses the head receiving portion. In the locking position, at least part of the clamping ring that faces the first end of the receiving part is exposed to the outside to facilitate movement of the clamping ring away from the first end of the receiving part.
