Abstract
A component of an artificial joint according to an exemplary aspect of the present disclosure includes, inter alia, a hollow tube including bone ingrowth material. Further, the hollow tube is selectively expandable. The bone ingrowth material allows the component to become biologically fixed to adjacent bone. Further, expansion of the hollow tube increases friction between the hollow tube and the adjacent bone, which increases stability.
Claims14
An artificial femoral component configured for use in a knee arthroplasty procedure, comprising:
- a hollow tube including bone ingrowth material, wherein the hollow tube projects from a posterior surface of the artificial femoral component in a posterior direction;
- and
- an anterior surface configured to provide an articulating surface of an artificial knee joint, wherein the anterior surface is on an opposite side of the artificial femoral component as the posterior surface.
An artificial femoral component configured for use in a knee arthroplasty procedure, comprising:
- a hollow tube including bone ingrowth material, wherein the hollow tube projects from a posterior surface of the artificial femoral component in a posterior direction,
- wherein the posterior surface includes a proximal planar surface, a distal planar surface, and a planar chamfer surface between the proximal planar surface and the distal planar surface,
- wherein the hollow tube projects from one of the proximal planar surface and the planar chamfer surface,
- wherein the hollow tube is a first hollow tube and the artificial femoral component further comprises a second hollow tube,
- wherein the first hollow tube projects from the proximal planar surface, and
- wherein the second hollow tube projects from the planar chamfer surface.
An artificial joint component configured for use in an arthroplasty procedure, comprising:
- a hollow tube including bone ingrowth material, wherein the hollow tube is selectively expandable;
- and
- an anterior surface configured to provide an articulating surface of an artificial joint, wherein the hollow tube is arranged on an opposite side of the artificial component as the articulating surface.
