FEMORAL COMPONENT FOR AN IMPLANTABLE HIP PROSTHESIS

摘要

An orthopaedic hip prosthesis includes a femoral head component including a spherical surface shaped to engage a prosthetic acetabular component. A femoral stem component, has a first shell including a neck configured to be secured to the femoral head component and an elongated body extending distally from the neck, the first shell including a polymeric material. A core is positioned in the first shell, the core including a first core body extending into the neck of the first shell and a second core body extending into the elongated body of the first shell, the core being formed from a material having a high tensile strength and a high elastic modulus. A second shell extends over a proximal section of the elongated body of the first shell, the second shell being formed from a metallic foam.
