    摘要: The invention relates to a bone implant for joint endoprostheses with a collarless, truncated-cone-shaped shaft (3) which can be inserted into a recess (1) of a bone (2) and which supports a joint piece (7), which shaft (3) has a surface area (8) with a plurality of protrusions (9). It is provided by the invention that the protrusions (9) are formed by local teeth rising from the surface area (8), the distal areas of which have at least one cutting or abrading edge or surface (10) for abrading the bone (2) during insertion or for creating a space for the protrusions (9) so that they can be placed into the bone (2).

    摘要: The bone implant for prostheses, particularly joints or joint members, preferably joints of the human locomotor system and especially the walking system, contains a shaft insertable into a cavity in a bone. The shaft has a total cross-section increasing from its diaphysis-associated distal end to its metaphysis-associated proximal end. Preferably, The shaft possesses in the region of the metaphysis-associated proximal end an integrally formed or separate intermediate piece at which the joint or joint member can be arranged. The shaft is preferably immediately and securely anchored in the bone and particularly is made of a metallic material. The shaft possesses an oblong rotationally symmetrical shaft body having an outer surface generated by, if desired, a longitudinally curved or preferably a substantially straight generatrix. The shaft body substantially has the shape of a truncated cone. Its outer surface can be contracted with the bone without the presence of a bonding agent and possesses a plurality of projections extending substantially parallel to the generatrix generating the outer surface. The projections preferably extend along the total length of the shaft body and are preferably mutually similar. The projections have edges extending preferably radially outwardly from the main axis of the shaft body, and preferably have the form of a knife edge.

    摘要: An expandable endoprosthesis for a joint and adjacent bone parts has first and second joint component parts. The second component has a part at one end thereof for a portion of a joint. The second component has a telescoping stem coupled to its joint part for attachment to a long bone. The telescoping stem has an inner and an outer member axially adjustable with respect to one another by means of a threaded spindle and a threaded spindle nut attached respectively to either the inner or outer member. A pinion gear is attached to either the spindle or spindle nut for rotation therewith. An indexing system is provided to rotate the pinion a predetermined amount upon movement of the first and second joint components towards one another after implantation and thereby lengthen the second joint component stem.
