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 &agr; which restores the valgity of the leg.
