Femur part of hip replacing prosthesis, comprising longitudinal steps integrated in upper end

摘要

The prosthesis (10) is of a slightly tapering shape, wider at the top, and fitted with a cylindrical extension (16) for being joined to a second component. Several longitudinal positioned steps (12), at first increasing in height (14) but decreasing again (15) close to the extension (16), are formed into the material at the upper end of the prosthesis (10), matching the shape of a complementary area inside the hollow bone.
