Abstract: An implant for use for adjacently arranged bone plates is described, having a first bearing part, a second bearing part and a coupling element for tension-proof coupling of the first bearing part to the second bearing part. The bearing parts are curved concavely and comprise a plurality of ribs, which extend radially outwards from a central portion of the respective bearing part. The upper bearing part comprises a main body and an insert connected thereto by means of at least one connecting element. The connecting element is supported against the coupling element with regard to movement into a release position. The upper bearing part additionally has a deflectable fixing element, which is supported against the upper bearing part in the event of movement of the upper bearing part away from the lower bearing part.

Abstract: The invention relates to a sleeve system for use in combination with a plurality of different types of sleeve for surgical operations, particularly in the central region of the face. Said sleeve system comprises a sleeve handle, which is constructed for the purpose of mounting different types of sleeve, and a first arrangement for interacting with a mounted sleeve of a first type, and also a second arrangement for interacting with a mounted sleeve of a second type. The first arrangement prevents rotation of a sleeve of the first type, relative to the handle, and the second arrangement makes possible guided rotation of a mounted sleeve of the second type, relative to said handle.

Abstract: Compression bone screw and screwdriver blade therefor A compression bone screw is described, with a shank having two opposite shank sections along its axial extent, a first thread being connected in a rotationally fixed manner to the shank in the region of the first shank section. The shank has at least one latching element for rotatably coupling a threaded component bearing a second thread to the second shank section. The invention furthermore relates to a screwdriver blade for the compression bone screw.
