Abstract
An intervertebral implant is shaped in the form of a hollow cylinder and has a cover face, a base face, a hollow cylinder wall with an outer lateral area and an inner lateral area, as well as a hollow cylinder central axis. The implant is formed at least 95 percent by volume of a radiolucent material which has a modulus of elasticity of between 1 and 20 GPa. Postsurgical observation is permitted by means of X-rays, and at the same time the implant has a high degree of biocompatibility.
