摘要： An implant for the spinal column for fixing the vertebrae, especially the cervical vertebra, on the anterior side, i.e., on the side of the esophagus, wherein the implant has screw holes for screwing together with the vertebra and has a multi-component design, and has at least two mounting plates, which are provided with at least two screw holes. The mounting plates are connected by an articulated bearing each to a spindle having right-hand and left-hand, self-locking threads with an angular shaft piece for actuating the spindle, wherein the mounting plates have a ribbed area on the side facing the vertebral bone W. The articulated bearing includes a bearing bush extending outwardly from each mounting plate and a bearing pin which has a threaded hole for engaging the spindle. The bushing has a hole allowing the spindle to pass through the bearing bush wherein pin is moveable within the bearing bush.

摘要： A medical technical compression implant (1) for the surgical repair of damage to the spine, especially in the cervical region, includes two clamp jaws (3, 4), which are directed toward each other, are hook-shaped, are connected by a threaded spindle (2), and can be compressed while reducing the distance (B) between them. A wrench profile (9) for attaching a rotating tool in an interlocking manner is arranged at the threaded spindle (2) between two threaded sections (7, 8) with right-hand threads and left-hand threads, respectively. Both the clamp jaws (3, 4) have threaded nuts (5, 6), which are pivotably mounted from bodies, with diametrical threaded bores for screwing on the threaded sections (7, 8). The threaded nuts are mounted in cylindrical transverse bores of the clamp jaws (3, 4). The bore walls (21) are provided with diametrical openings (22, 23) for passing through the threaded sections (7, 8) of the threaded spindle (2). The threaded spindle (2) has, at both ends, an outwardly tapering cone (12, 13) each, which brings about pivoting of the clamp jaw (3, 4) around the axis of the transverse bore in the pulling direction, in cooperation with the inner edge or inner surface of the opening (22) designed as a radial bore.A manipulating device in the form of a special expanding forceps is provided for implantation.
