Abstract
Abstract Disk-shaped implant (2) for reinforcing of adjacent vertebrae characterised in that the implant (2) has a disk shaped core (4) made of solid metal having an open-pored or open-celled metal structure (6) provided on the surfaces of the core (4). The advantage of the invention is that bone tissue is conserved while effective reinforcement is achieved. <IMAGE>
