In order, in an intervertebral implant having a core made of a swellable material and having a vertebral-body locating face on its top and/or bottom side, which is connected to the swellable core, to reduce the shearing forces between the swellable core and the vertebral-body locating face during swelling of the swellable core, it is proposed that the vertebral-body locating face comprises a plurality of support elements, which are respectively anchored adjacent to one another and individually in the core, and a plurality of mutually separate locating elements, which are disposed adjacent to one another and outside of the core and which are carried by the support elements and are movable relative to one another in the plane of the vertebral-body locating face.

Intervertebral implant

The invention is related to an implant, in particular a bone replacement implant for insertion into a bone cavity, or an intervertebral implant for insertion between two adjacent vertebral bodies of a human or animal spine. The implant can be brought from a normal position, in which the implant encompasses a maximum total volume, into an insertion position, in which the implant encompasses an insertion volume, which is smaller than the maximum total volume. Moreover, the implant has a plurality of cavities in fluidic connection with one another, and a net volume encompassed in the normal position by the plurality of cavities in fluidic connection with one another is smaller than the maximum total volume, which allows insertion of the implant through as small as possible an opening in a human or animal body while maintaining a high inherent stability.
