In order to improve an implant for the dorsal stabilization of a human or animal spinal column, comprising an attachment device for placing in position against and/or fixing to spinous processes of adjacent vertebrae of the spinal column, such that it can be used for the dynamic dorsal stabilization of the spinal column, it is suggested that the implant comprise at least one spacer element which is associated with the attachment device and designed in such a manner that it alters its external shape and/or its elastic properties as a result of a change in ambient conditions and/or forces acting on it. Furthermore, an improved implant system for the dorsal stabilization of a human or animal spinal column is suggested.
