摘要:
An orthopaedic prosthesis for a patient includes a metallic foam shell having a first elastic modulus, the metallic foam shell having an outer surface that engages a patients bony anatomy. A metallic has including a neck positioned proximal of the shell and a body that extends through the shell, the core having a second elastic modulus greater than the first elastic modulus. When the orthopaedic prosthesis is viewed in a transverse plane extending through the shell and the core, (i) a first thickness is defined between a medial-most point of the outer surface of the shell and a medial-most point of a medial surface of the core, and (ii) a second thickness is defined between a lateral-most point of the outer surface of the shell and a lateral-most point of a lateral surface of the core, the first thickness being less than the second thickness.
