Thigh stump endoprosthesis for an exoprosthetic treatment
First Claim
1. A thigh stump endoprosthesis for a thigh stump having a femur stump, the thigh stump is disposed in a shaft, and an artificial lower leg is connected to the shaft, the endoprosthesis comprising:
- a stem part having a first end and a second end, said first end is set into the femur stump;
an open-mesh, three-dimensional lattice covering at least partially the stem part;
a conical adapter on the second end of the stem part;
a condyle replacement modeled to the shape of natural condyles of a knee joint and coupled to the stem part; and
a wedge-shaped base connected to the condyle replacement.

Abstract
The invention relates to a thigh stump endoprosthesis for an exoprosthetic treatment of a patient whose leg has been amputated in the thigh area, whereby the thigh stump can be pulled into a shaft to which the replica of a lower leg part and foot part of the prosthesis is attached. The inventive prosthesis includes a proximal shaft part which can be inserted inside a femur stump, whereby the shaft part is at least partially covered by an open-mesh three-dimensional spatial network structure, and includes a conical adapter on the distal end thereof. A condyle replacement which re-creates the shape of natural condyles of a knee joint can be coupled to the shaft part by means of said adapter. A cuneiform support can be joined to the condyle replacement with a wedge angle α which restores the valgity of the leg.
