The invention relates to a contact device for a bone screw, wherein, in an implanted end state of the arrangement of bone screw and contact device, a first part of the contact device is arranged outside a cavity and a second part is arranged inside the cavity of the bone screw, the parts forming counterelectrodes, and the second part electrically contacts the bone screw while the first part is isolated from the bone screw, wherein the contact device has a cavity with a voltage source whose poles electrically contact each of the first part and second part directly or indirectly. In order to improve such a contact device, particularly in respect of the volume available for electrical components, it is proposed that the first part of the contact device is arranged proximally in an implanted end state of the arrangement of bone screw and contact device. |
