Hampton C, et al. - Fretting and corrosion in retrieved oxidized zirconium (OxZr; OXINIUM, Smith & Nephew, Memphis, Tennessee) femoral heads were determined and compared with those from a matched cohort of cobalt-chromium (CoCr) femoral heads. Researchers retrieved a total of 28 OxZr femoral heads during revision total hip arthroplasty (THA) and matched these to 28 retrieved CoCr heads according to patient demographics. Outcomes of retrieval analysis revealed a decreased amount of fretting and corrosion of OxZr femoral heads compared to CoCr femoral heads. They suggest that taper damage could be effectively reduced with OxZr.
