Abstract

The invention relates to an implant in the form of a bone-connecting device with an implant carrier, having at least two structure carriers for stimulating bone growth, the structure carriers can move relative to one another so that, due to a loading of the implant, a relative movement of the structure carriers occurs, the structure carriers furthermore contain structure elements that are arranged so that they define a plurality of partially open intermediate spaces, wherein a volume defined by these intermediate spaces and an immediate environment is deformed by the implant load, and a strain in the intermediate spaces and its immediate environment resulting from the deformation lies in the physiological range for bone growth.
