Abstract:
A vertebral column replacement body comprising first and second anchoring sides each adapted to face in a mounted state of the vertebral column replacement body an adjacent vertebra, wherein each of the anchoring sides comprises a tooting for preventing displacement in the ventral or dorsal directions, further comprising two body elements mounted so as to be slidingly guided relative to each other and transversely of the anchoring sides, wherein, when a desired relative position between the body elements is reached, a first of the body elements is configured to be braced against a second of the body elements by radially widening the first body element, wherein the first body element comprises a plurality of segments extending approximately parallel to an axis of the vertebral column replacement body and away from the first anchoring side, further comprising a tightening screw extending radially through a threaded bore of one of the segments of the first body element and acting transversely of a direction of extension thereof for bending the segments relative to each other in a radial direction against a wall of the second body element extending away from the second anchoring side, wherein the tightening screw is configured to place the segments of the first body element in tight contact with the wall, wherein the first body element has a first segment, a second segment and a third segment, and wherein the tightening screw extends through the first segment and the front end of the tightening screw protrudes into an area between the second and third segments for simultaneously radially acting on the segments.
