Abstract:
A polyaxial bone anchoring device includes a receiving part configured to be pivotably connected to a head of an anchoring element, the receiving part having a channel for receiving a rod and an accommodation space having an opening for accommodating the head, and a sleeve-like insert piece having a sleeve axis and a spherical segment-shaped outer surface portion. The insert piece is configured to be positioned around a portion of the head in the receiving part and to pivot in the receiving part, and includes a first part and a separable second part configured to be connected with the first part by a connection structure configured to permit translational movement between the first part and the second part in a direction transverse to the sleeve axis, while preventing movement between the first part and the second part in a direction parallel to the sleeve axis.

Claim (Index 27):
A method of coupling a rod to a bone via a polyaxial bone anchoring device, the bone anchoring device comprising an anchoring element having a shank for anchoring in the bone and a head, a receiving part configured to be pivotably connected to the head and having a first end and a second end, a central axis extending through the first end and the second end, a channel transverse to the central axis for receiving a rod, and an accommodation space for accommodating the head, the accommodation space having an opening at the second end, a sleeve-like insert piece configured to be positioned around a portion of the head in the receiving part and to pivot in the receiving part, and a pressure member positionable at least partially in the accommodation space and configured to contact and exert pressure onto the head while being spaced apart from the insert piece, the pressure member having an outer surface and a groove formed in the outer surface, and a fixation element, the method comprising:\n inserting the shank of the anchoring element into the bone; adjusting an angular position of the receiving part relative to the anchoring element, wherein when the head, the insert piece, and the pressure member are in the receiving part, a first portion of the outer surface of the pressure member is positioned axially between the groove and the second end of the receiving part, and the insert piece is pivotable relative to the pressure member to a first position where part of the insert piece extends into the groove to a radial position that is closer to the central axis than the first portion of the outer surface of the pressure member is to the central axis; inserting the rod into the channel of the receiving part; and advancing the fixation element in the channel of the receiving part to urge the rod towards the pressure member for the pressure member to exert pressure onto the head to lock the angular position of the receiving part relative to the anchoring element and to lock the rod in the channel of the receiving part.
