Claim 0:
1. A femoral orthopaedic prosthesis, comprising:
a metallic core extending from a proximal end to a distal tip, the metallic core including (i) a neck that is positioned at the proximal end and is configured to receive a prosthetic femoral ball, and (ii) an elongated stem extending distally from the neck to the distal tip, and
porous foam coupled to the metallic core,
wherein the stem includes:
a proximal section extending distally from the neck,
a distal section extending proximally from the distal tip,
a medial beam having a proximal end connected to the proximal section, a distal end connected to the distal section, an anterior side, and a posterior side,
a lateral beam spaced apart from the medial beam and having a proximal end connected to the proximal section, a distal end connected to the distal section, an anterior side, and a posterior side, and
a cross-beam having a first end connected to an inner wall of the medial beam, a second end connected to an inner wall of the lateral beam, an anterior side that extends from the first end to the second end and that is offset posteriorly relative to the anterior sides of the medial beam and the lateral beam, and a posterior side that extends from the first end to the second end and is offset anteriorly relative the posterior sides of the medial beam and the lateral beam; and a central beam that extends between the medial beam and the lateral beam, wherein the central beam includes an anterior surface that is substantially planar with the anterior sides of the medial and lateral beams and a posterior surface that is substantially planar with posterior sides of the medial and lateral beams,

wherein a first portion of the porous foam is positioned in an anterior notch that is defined between the proximal section, the distal section, the inner walls of the medial and lateral beams, and the anterior side of the cross-beam and wherein the first portion covers the anterior side of the cross-beam, and
wherein a second portion of the porous foam is positioned in a posterior notch that is defined between the proximal section, the distal section, the inner walls of the medial and lateral beams, and the posterior side of the cross-beam and wherein the second portion of the porous foam covers the posterior side of the cross-beam, and wherein the central beam separates each of the anterior notch and the posterior notch into respective first and second sections.
