Abstract
A modular endoprosthesis having a plurality of shaft elements, wherein a first shaft element has a longitudinal axis, an outer wall, a circumferential indentation and a substantially conical bore. The bore has an open mouth and a closed base. The circumferential indentation is located on the outer wall close to the open mouth of the conical bore for the purpose of reducing mechanical stresses in the vicinity of the mouth of the bore when the endoprosthesis is subjected to a bending force. A second shaft element has a longitudinal axis, an outer wall and a substantially conical pin adapted to fit the bore in the first shaft element, for joining the two shaft elements together with a conical socket connection.
