Oxinium Femoral Heads
Oxinium Oxide Zirconium is a patented metal alloy developed by Smith & Nephew as an alternative to other metal-on-metal hip and knee replacement devices. According to descriptions, Oxinium femoral heads are produced using a proprietary oxidization process that creates a ceramic surface while retaining an underlying metal structure. Cross-linked polyethylene (XLPE) liners are typically used with the Oxinium femoral heads. The company has claimed that the Oxinium construction process reduces the number of XLPE particles created under various conditions when compared with cobalt-chrome (CoCr) alloy devices. 2
