Abstract:
This invention relates to a metal composite orthopedic device such as an articulating spinal spacer (60, 90). The device can comprise a metallic substrate (62, 96) cladded or joined to one or more metallic layer(s) (68, 98). The substrate and metallic layer(s) can be selected of different metals and metal alloys to provide desired wear performance, imaging characteristics and optionally to serve as a reservoir for therapeutic agents.
