  "abstract": "A prosthesis part can be implanted without the use of cement. The prosthesis part comprises: a cage structure, which unites with the spongy substance of the bone; a carrier plate which is connected to the cage structure; and a carrier post for a joint part. The carrier post is supported by the carrier plate. The carrier plate has openings through which a severing instrument, such as a chisel or milling cutter, is introducable in order to separate the cage structure at least to a large extent from the cortical substance of the bone.",
  "claims": [
    "1. A prosthetic part comprising an anchorage section (26, 50) that is introducable into a bone recess (14), said anchorage section comprising at least partially a cage structure (26), a plate section (16) which extends in a lateral direction beyond the anchorage section (26, 50), and a supporting section (22) for a joint part (24), wherein the plate section (16) is provided on its upper side with markers (70) which are each aligned with a supporting-plate attachment-point of an anchorage pillar (28 to 34) pertaining to the cage structure(26).",
    "2. The prosthetic part as set forth in claim 1, wherein the markers comprise notches (70) which center a drill-point.",
    "3. A prosthetic part comprising an anchorage section (26, 50) that is introducible into a bone recess (14), said anchorage section comprising at least partially a cage structure (26), a plate section (16) which extends in a lateral direction beyond the anchorage section (26, 50), and a supporting section (22) for a joint part (24), wherein the plate section (16) is provided with at least one opening (60, 62) or at least one indentation (64) in the vicinity of the edges of the plate section, through which a severing instrument is introducible to cut a connection between the anchoring section and corticalis substance of a bone, wherein the plate section (16) comprises a marginal region having a circumferential arrangement of indentations (64 a, 64 b), and, wherein the circumferential arrangement of indentations (64 a, 64 b) comprises a succession of indentations (64 a, 64 b) of differing depths.",
    "4. The prosthetic part as set forth in claim 3, wherein the at least one opening (60, 62) or the at least one indentation (64) is convex.",
    "5. The prosthetic part as set forth in claim 3, wherein the openings (60, 62) or the indentations (64) are convex.",
    "6. The prosthetic part as set forth in claim 3, wherein the circumferential arrangement of indentations (64 a, 64 b) comprises a succession of indentations (64 a, 64 b) of differing depths."
