Abstract
A bone anchoring device includes a bone anchoring element having a head and a shaft, a receiving part for coupling the bone anchoring element to a stabilization element, the receiving part having a bore having a bore axis, a seat member configured to be arranged in the bore and to be rotatable around the bore axis, the seat member forming a seat for polyaxially holding the head, the seat member being configured to allow a greater pivot angle of the bone anchoring element in a first direction compared to other directions when the bone anchoring element and the seat member are in the receiving part, and a pressure member configured to contact the head to exert pressure onto the head, and to be connected to the seat member, such that the pressure member is rotatable together with the seat member around the bore axis.
