BIOLOX delta is the newest ceramic composite material of the BIOLOX family and its use in hip devices represents a good alternative to Metal-on-Metal or Metal-on-Polyethylene coupling. Some Metal-on-Metal hip devices have shown chromium and cobalt release, which promoted toxic effects. Furthermore, the ceramic composite contains trivalent chromium, even if strongly bound to the alumina lattice. The present study is aimed at detecting any 'in vivo' release of chromium ions from BIOLOX delta… CONTINUE READING
