主权项

1. A bone-implantable prosthetic device, comprising:
an interface portion operative to interface the bone-implantable prosthetic device with an other structure; and a stem coupled to said interface portion, wherein the stem is structured for implantation to a desired depth into a bone tissue, and wherein the stem includes: a metallic body having a length corresponding to the desired depth of implantation; wherein said metallic body includes a support structure and a hollow pin, fin and/or lattice structure formed as a unitary structure and configured to transfer load between said stem and the bone tissue, wherein said pin, fin and/or lattice structure includes an outer ring shape that is integral with, disposed radially outward of, and fully encircles said support structure such that an offset is provided to create a space between the outer ring shape and the support, said pin, fin and/or lattice structure further including an inner ring shape that is integral with and fully encircles said support structure, the inner ring shape being disposed radially inward of the outer ring shape, and said pin, fin and/or lattice structure further including an intermediate ring shape that is integral with and fully encircles said support structure, the intermediate ring shape being disposed radially inward of the outer ring shape and outward of the inner ring shape.
