ABSTRACT:
The stem of the prosthesis is fixed in a medullated bone by means of a plurality of spacers which are distributed over the length of the stem. The spacers serve to stabilize the stem over the entire length of the stem within the bone cavity. Bone cement is charged into each peripheral opening defined between a pair of spacers via bores drilled transversely through the cortex of the bone in stages from the distal end toward the proximal end.
