Abstract
A plastic implant having a sliding core, such as an intervertebral endoprosthesis, is formed with a peripheral, preferably circumferential, channel that is configured to receive a radiographic contrast wire. The channel may be partially or fully closed to an outside portion of the sliding core and may include a restriction in the profile of the channel that acts to partially close the channel to the outside portion of the sliding core. The restriction may have a width that is less than the diameter of the radiographic contrast wire. The channel may also include an insertion opening adapted to accept the wire.
