Abstract
An intervertebral implant comprising a lower implant part, having a central axis and an apposition section, designed to rest against the covering surface of the adjacent lower vertebra and an upper implant part comprising a bore with an internal thread, a central axis and an apposition section, designed to rest against the covering surface of the adjacent upper vertebra. Specifically, the lower and upper implant parts are secured in relation to each other against rotation about the central axis and a threaded screw with an external thread is guided in the upper implant part and connected to the lower implant part, the external thread cooperating with the internal thread. The lower and upper implant parts, and the threaded screw lie coaxially along their common central axis, the threaded screw being connected to the lower implant part so that it is axially fixed but able to rotate.
