The invention concerns a linking piece designed to maintain a spacing between at least two anchoring elements screwed in vertebrae. It comprises at least: two rigid parts forming rods (12, 14) made in a first material, each having a first fixing portion (16, 18) adapted to be fixed into an anchoring element and a second securing portion (20, 22), said rods (12, 14) being located in the extension of each other and said securing portions (20, 22) opposite each other, and, a linking member (24) made in a second material with greater elastic deformability than the first material, linking said rigid parts (12, 14) by their securing portions (20, 22) opposite each other such that said linking piece (24) is adapted to be elastically deformed, whereby the vertebrae, maintained spaced apart from each other, are mobile relative to each other. |
