Claim 12:
13. An orthopaedic prosthetic component, comprising:
a base,
a porous three-dimensional structure attached to the base, the porous three-dimensional structure being configured to permit bone in-growth and having an outer surface boundary, wherein the porous three-dimensional structure includes a plurality of struts, and
a plurality of engagement studs extending outwardly along respective central axes of the engagement studs from the outer surface boundary of the porous three-dimensional structure, each engagement stud having a body and a respective impaction head that extends from the body, wherein the impaction head comprises a triangular prism having first and second parallel triangular faces that are spaced from each other, such that an outer impact tip, configured to engage a patient's bone, extends from an apex of the first triangular face to an apex of the second triangular face,
wherein each strut is shorter than each engagement stud,
wherein an imaginary plane that is perpendicular to the central axes intersects the plurality of engagement studs and the plurality of struts such that respective central strut axes of the struts are angularly offset with respect to the imaginary plane, and each engagement stud of a number of the plurality of engagement studs is 1) non-circular in cross section in the imaginary plane, and 2) rotated about its central axis at an angle of 90 degrees from others of the plurality of engagement studs in the imaginary plane, and
wherein the struts are elongate along the respective central strut axes.
