A medullary rod has a peripheral wall defining the outer shape of the medullary rod, and inwardly delimiting a hollow space. The medullary rod also has a plurality of first partitions. The first partitions are generally parallel to one another, extend between the inner side of the medullary rod located along the inner edge of the long bone after implantation, and the outer side of the medullary rod located along the outer edge of the long bone after implantation. Each of the first partitions is integral with the peripheral wall at these inner and outer sides of the medullary rod.

A stemmed implant comprises a proximal body with a distal shaft extending from the proximal body. The proximal body exterior may be spherical, conical, cylindrical, or another surface of revolution. The distal shaft comprises multiple longitudinal ridges which may originate from the proximal body as separate columns, or which may merge together. The distal shaft and/or the ridges may become narrower as they extend away from the proximal body.
