摘要 |
<p>An intervertebral disk prosthesis or the intervertebral implant has a cavity-like middle part with a longitudinal axis, an upper end, a lower end, an upper apposition plate, and a lower apposition plate. The upper apposition plate is placed on the upper end of the middle part such that it is perpendicular to the longitudinal axis. The upper apposition plate is suited for resting against the base plate of a vertebral body. The lower apposition plate is placed on the lower end of the middle part such that it is perpendicular to the longitudinal axis. The lower apposition plate is suited for resting against the cover plate of a vertebral body. The middle part has at least two coaxially arranged plate springs, which gives the middle part a progressive spring characteristic.</p> |
