Abstract: The disclosure relates to an implant system for promoting an osteosynthetic process at a gap between two bone fragments at a bone of an endoskeleton, in particular of a human mammal. In order to have available an implant system of this kind which allows patient-specific bone reconstruction of a bone, in particular an ulna and radius, wherein the gap between the two bone fragments created during the correction can be supplied with a patient-specific, accurately fitting artificial graft, a graft is provided, which can be inserted into the gap between the two bone fragments; an osteosynthesis plate is provided, which can be fastened to the bone and to the graft ; and a connection device is provided for connecting the graft and the osteosynthesis plate.

Abstract: The invention relates to a bone implant for attaching to on a surface of a bone, including a base body whose lower side and/or upper side correspond(s) substantially to a deformation-free bone outer contour, wherein the outer dimensions of the base body are chosen such that the base body covers a specifically introduced deformation region for obtaining autologous bone material completely, wherein in the base body at least one slot is provided which is dimensioned such that it guides a bone marking and/or bone processing tool inserted in the slot in use.
