Abstract:
A polyaxial bone anchoring device includes a bone anchoring element having a head and a shaft, a receiving part having a head receiving portion, a rod receiving portion, and a bore having a bore axis, and a pressure member movable in the bore and having a first surface for engaging the head, wherein the pressure member is movable to a first position where friction between the first surface and the head generates a preload on the head to maintain the shaft at a temporary angular position relative to the receiving part, and wherein the pressure member is configured to engage the receiving part to generate a holding force for holding the pressure member at the first position without a positive lock, and wherein the pressure member is movable in and out of the first position by applying an axial force on the pressure member greater than the holding force.

Claim (Index 20):
A polyaxial bone anchoring device comprising:\n a bone anchoring element having a head and a shaft for anchoring to a bone; a receiving part for coupling the bone anchoring element to a rod, the receiving part having a first end and a second end, a head receiving portion at the second end with an accommodation space for accommodating the head, and a rod receiving portion at the first end defining a bore in communication with the accommodation space, the bore having a bore axis; and a one-piece pressure member movable in the bore and comprising a first surface for engaging the head, a second surface for engaging a rod, and an outer surface; wherein when the bone anchoring element and the pressure member are in the receiving part, the pressure member is configured to assume and be held at a first position where friction between the first surface and the head generates a preload on the head to maintain the shaft at a temporary angular position relative to the receiving part, and to a second position different from the first position where the head is locked relative to the receiving part; and wherein the receiving part comprises a separate insert that is positionable in a recess formed in a side wall of the receiving part, such that when the pressure member is at the first position, the separate insert of the receiving part exerts a holding force on the outer surface of the pressure member to restrict movement of the pressure member towards the first end of the receiving part, wherein at least part of the holding force acting on the outer surface of the pressure member is directed radially relative to the bore axis to generate friction between the pressure member and the receiving part, and wherein the pressure member is movable out of the first position towards the first end of the receiving part by applying a sufficient axial force on the pressure member while a position of the separate insert relative to the receiving part remains substantially constant.
