Which metal ions are virtually eliminated from Oxinium?

Which metal ions are virtually eliminated from Oxinium?

• A. Nickel, Cobalt, Chromium
• B. Titanium, Vanadium, Aluminum
• C. Iron, Copper, Zinc
• D. Zirconium, Niobium, Tantalum

Answer: (A)

Oxinium reduces metal ion release by using a zirconium-based alloy with a ceramic oxide surface. That ceramic-like barrier is highly resistant to wear and corrosion, so the ions most often released by traditional metal implants—nickel, cobalt, and chromium—are virtually eliminated at the articulation. The material’s core contains zirconium (and alloying elements like niobium), but the surface design isolates the bulk metal from body fluids, preventing those problematic ions from leaching out.
