Flexible linking piece for stabilising the spine

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