A device for stimulating the osteogenesis of a traumatized bone is mounted
on a bone stabilizing implant. The device comprises a first component
part comprising a first electrode, an isolating element, which is mounted
at the first component part and a second component part comprising a
second electrode. The second component part is mounted at the isolating
element such that the first electrode and the second electrode are
electrically isolated from each other. The power generation unit is
electrically coupled both to the first electrode and to the second
electrode. The first component part is designed to be attached to the
implant in such a manner that the second component part intrudes in a
region defined by a trauma within the bone. Further described is a
medical system for stimulating the osteogenesis of a traumatized bone,
the medical system comprising a bone stabilizing implant, which is
adapted to be fixed to the traumatized bone, and an osteogenesis
stimulation device as has been described above is mounted thereon.
