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

11. A femur endoprosthesis kit for an artificial hip joint, comprising:
-
a shell (1) which can be implanted without cement in an upper region of a femur below its greater trochanter, a proximal end (8) of the shell being connectable with an adapter (2) for accommodating an artificial spherical joint part (20), the shell including an exterior which is at least partially covered with an open-meshed three-dimensional spatial lattice structure (9); a draw plate (3) adapted to be mounted on an opposite side of the femur from the shell; and a draw-in screw (4) which is adapted to be fastened through the draw plate and inserted in an interior of the shell through a through bore (5) in a distal end (6) of the shell such that the draw-in screw can be screwed directly into a thread provided in the shell interior in order to draw the shell into an implantated position during surgery to install the femur endoprosthesis.
