A femur endoprosthesis for an artificial hip joint includes (a) a shell (1) which can be implanted without cement in the upper region of a femur below the greater trochanter, the proximal end (8) of the shell being connectable with an adapter (2) for accommodating an artificial spherical joint part (20), wherein the exterior of the shell is at least partially covered with an open-meshed three-dimensional spatial lattice structure (9), and (b) a draw plate (3) in which a draw-in screw (4) can be fastened, which can be inserted in the interior of the shell through a through bore (5) in its distal end (6), and which can be screwed in with a thread (7) provided therein.

Femur endoprosthesis for artificial hip joint

In a tibial portion of a knee joint endoprosthesis with a securing shank (10) to be inserted into the medullar cavity of the tibia, which, on one end, is provided or not with a tibia condyle terminal plate for the attachment of the articular parts of the prosthesis, the securing shank (10), in order to achieve a firm fit of the implant after the implantation, comprises a cylindrical sleeve (11) that is insertable into a cylindrical slotted drilled hole (201) of the tibia with an interior (12) accommodating the spongiosa nucleus (205) of the slotted drilled hole (201), and is fabricated from a metallic material or some other suitable, body-compatible material, while the securing shank (60) is disposed at a right angle to the terminal plate (20) extending parallelly to the horizontal or slightly inclined ostectomy area (206) (FIG. 1).

Tibial component of a knee joint prosthesis

The femoral bone-hip joint endoprosthesis is characterized by the cavity construction of the prosthesis shank (10), by the ovaloid-conical aperture of the prosthesis shank and by the ovaloid-conical aperture of the upper prosthesis shank end for the accommodation of a cone plug connection (20).
