BACKGROUND As a consequence of use of metal-on-metal hip arthroplasties some patients have precised revision for pain or metal hipersensivity reactions among other causes. We propose to salvage monoblock acetabular component and femoral component using a dual-mobility head and perform a lower morbidity operation in young patients preserving host bone stock in cases with well fixed and positione...

To improve the tribocorrosion performance of 316L stainless steel (SS), multi-layer (1, 2 and 3 layers) Fe-based alloy coatings were manufactured by laser cladding amorphous powder on SS, corrosive wear behavior was investigated against Alumina ball in Ringer's solution. With increase layer number, content body-centered cubic (BCC) phase increases, hardness also improved. The volume loss rate S...

Abstract Corrosion at the taper/trunnion interface of total hip replacement (THR) often results in severe complications. However, underlying mechanisms biotribocorrosion during long-term walking gait cycles remain to be fully understood. In this study, a joint simulator was therefore instrumented with an electrochemical cell for in-situ monitoring tribocorrosion evolution metal-on-polyethylene ...
