Abstract (en)
[origin: WO2016192877A1] The invention relates to a uniplanar bone anchoring element (10) comprising an anchoring screw (12) with a bone thread (14) and a screw head (18), which is flattened on at least one side (17); a receiving element (20) that has a through-bore which tapers in a lower region (21) and in which the anchoring screw (12) can be received; and two limbs (25, 26) which extend upwards and which comprise a threaded profile (27) in an upper region, said threaded profile being designed for screwing on a securing screw. The receiving element (20) has an inner groove (24) which partly runs at least in the circumferential direction in the seat region of the anchoring screw head (18). The bone anchoring element also comprises a bearing element (40) for inserting into the inner groove (24) of the receiving element (20). The bearing element (40) is partly flattened on at least one side (47), and the groove and the bearing element are designed in a complementary manner such that the bearing element is positioned in the groove in a specified position.
