Oxinium bearings- Fact or Fiction
Oxinium or otherwise “oxidised zirconium” was suggested as a good bearing surface by Bourne in his article in CORR 2005. These oxinium surfaces are derived from a zirconium base that is heated and then infused with oxygen, transforming the outermost layer into a ceramic shell This surface possibly combines the fracture resistance of metal, with […]
New test detects early osteolysis after arthroplasty
