Abstract
A bone anchoring element () for anchoring an external device in a bone is described. A head () capable of connection to the external device is provided with a shaft () that can be anchored in a bone. A predetermined section of the shaft () has a bone thread (). Moreover, the shaft () also has at least one bone thread-free surface () 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 (), thus provided, is pressed or soft-hammered into a hole () 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.
