Publication number: 20210244456Abstract: A bone anchoring element comprising a shaft (2) for anchoring in a bone, with a plurality of barb elements (7) arranged in at least one helical line around the shaft axis (M) is described, wherein said barb elements are elastically movable relative to the shaft. The bone anchoring element (1) is easy to press into a core hole bore in a bone. The barb elements (7) act in a similar manner as do the threads on a conventional bone screw and thus provide for depth positioning. Moreover, the barb elements at the same time secure the bone anchoring element and prevent it from sliding-out.Type: ApplicationFiled: December 30, 2020Publication date: August 12, 2021Inventors: Lutz Biedermann, Wilfried Matthis, Helmar Rapp

Patent number: 10285744Abstract: A bone anchoring element (1) for anchoring an external device in a bone is described. A head (2) capable of connection to the external device is provided with a shaft (3) that can be anchored in a bone. A predetermined section of the shaft (3) has a bone thread (5). Moreover, the shaft (3) also has at least one bone thread-free surface (6,7; 11,12; 16,17; 21,22,23) that extends from a first end to a second end of the predetermined section essentially along the direction of the shaft axis. The bone anchoring element (1), thus provided, is pressed or soft-hammered into a hole (8, 28) previously generated in the bone and fixed in the bone by rotation by a predetermined angle. If the bone anchoring element has to be removed this can be achieved by unscrewing it in the standard fashion. The disclosure also describes methods for using the bone anchoring element.Type: GrantFiled: February 16, 2016Date of Patent: May 14, 2019Assignee: BIEDERMANN TECHNOLOGIES GMBH & CO.
