Abstract

A femur endoprosthesis for an artificial hip joint is provided with a stem (1) which can be implanted without cement in the upper region of a femur below the greater trochanter. The proximal end (8) of the stem is connectable with an adapter (2) for accommodating an artificial spherical part of a joint (20). The exterior of the stem is at least partially covered with an open-meshed three-dimensional spatial lattice structure (9). A distal end of the stem is bent caudally with a caudally oriented step (31) in the transition area and constructed as a stem end (30), which is also at least partially covered with an open-meshed three-dimensional spatial lattice structure (9).
