Claims21
A medical implant, comprising:
- a ceramic body having a shape operable for use in the implant;
- and a plurality of solid metal wires embedded in the ceramic body and dispersed throughout the implant forming an internal matrix operable to minimize crack propagation, wherein each of the plurality of metal wires comprises a first region contained inside of the ceramic body and a second region extending a distance outside a first surface of the ceramic body, the plurality of wires forming a matrix of the second regions to promote bone ingrowth.
A medical implant, comprising:
- a ceramic body comprising a ceramic material and having a shape operable for use in the implant;
- and a plurality of solid metal wires embedded in the ceramic material of the ceramic body and dispersed throughout the implant, wherein each of the solid metal wires comprises a first region contained inside of the ceramic material forming a support matrix operable to minimize crack propagation, and a second region comprising a projection that extends a distance outside from a first surface of the ceramic body for receiving a porous metal spray.
