Abstract
Official abstract text for this publication.
An orthopaedic prosthesis for use in a hip replacement surgery includes an implantable stem component. The implantable stem component includes a core and a shell extending over the core. The shell includes a polymeric material and is configured to receive a femoral head component. Metal foam may extend over a portion of the shell.
First claim
Opening claim text (preview).
The invention claimed is: 1. An orthopaedic hip prosthesis, comprising: a femoral head component including a spherical surface shaped to engage a prosthetic acetabular component, a distal surface having an opening defined therein, and a polymeric inner wall extending inwardly from the opening to define a tapered bore of the femoral head component, and a femoral stem component including a distal tip and a tapered proximal post that is sized to be positioned in the tapered bore of the femoral head component to taper lock the femoral stem component to the femoral head component, wherein the femoral stem component further comprises: a polymeric shell including the tapered proximal post, and a core including a first core body extending into the tapered proximal post of the polymeric shell, the core having a high tensile strength and a high elastic modulus. 2. The orthopaedic hip prosthesis of claim 1 , wherein the core is completely surrounded by the polymeric shell. 3. The orthopaedic hip prosthesis of claim 1 , wherein the femoral head component includes a metallic body having an aperture defined therein. 4. The orthopaedic hip prosthesis of claim 3 , wherein the polymeric inner wall comprises a polymeric insert positioned in the aperture of the femoral head component. 5. The orthopaedic hip prosthesis of claim 4 , wherein the polymeric insert includes the opening defined in the distal surface of the femoral head component and the polymeric inner wall extending inwardly from the opening such that the tapered bore of the femoral head component is defined in the polymeric insert. 6. The orthopaedic hip prosthesis of claim 1 , wherein: the polymeric inner wall comprises a polymeric insert including the opening defined in the distal surface of the femoral head component, and the polymeric inner wall extends inwardly from the opening such that the polymeric insert defines the tapered bore of the femoral head component.
