Abstract
The invention relates to a femur stem (10) of a hip joint endoprosthesis. The cross-section of the femur stem twists from its proximal to its distal region in such a way that the transverse-oval cross-section in the proximal region turns towards the distal direction such that the cross-section is sagittal-oval in the distal region. The femur stem according to the invention can easily be introduced into the medullary canal and is optimally adapted to the shape of the medullary canal.
