Document Type and Number:
Japanese Patent JPH064082
Kind Code:
B2
Abstract:
A prosthetic part for use as an orthopaedic implant has a cast metal base member 20 min and a tissue ingrowth surface spaced outwardly therefrom. The tissue ingrowth surface is in the form of a cast metal lattice element 10 min which covers at least a part of the outer surface of the base member 20 min . The cast metal lattice element 10 min is cast simultaneously and integrally with the base member from the same metal. This metal may be any well known castable material for ortho-paedic implants such as Vitallium or titanium. The lattice element 10 min is in the form of a grid-like mesh which includes spacer members 16 min cast integrally with the wire mesh and the base member to space the lattice element 10 min a predetermined distance above the prosthesis surface 18 min . An investment casting technique wherein a meltable material is coated with a ceramic casting shell is utilized to produce the integrally cast orthopaedic implant and tissue ingrowth surface.
