Abstract: An intramedullary nail system including an elongated nail member comprising a cavity and electrically conductive at least in part, a coil assembly, a first electrode connected to a first pole of the coil assembly and a second electrode connected to a second pole of the coil assembly. To improve such an intramedullary nail system the coil assembly is provided in an end cap assembly that is proximally releasably connected to the nail member and with at least one electrically conductive outer contact surface. At least one section of the electrically conductive outer contact surface forms the first electrode and at least one section of the nail member forms the second electrode.

Abstract: 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.

Abstract: The invention relates to an intramedullary nail system including an elongated nail member comprising a cavity and electrically conductive at least in part, a coil assembly, a first electrode connected to a first pole of the coil assembly and a second electrode connected to a second pole of the coil assembly. To improve such an intramedullary nail system particularly as regards its convenience in handling and flexible application during the operation, its stability, its biological effect, its therapeutical effectiveness and its economy it is provided for that the coil assembly is provided in an end cap assembly proximally releasably connected to the nail member with an outer contact surface being electrically conductive at least in part, that the contact surface is electrically insulated from the nail member, that at least one section of the contact surface forms the first electrode and that at least one section of the nail member forms the second electrode.
