[Nickel, chromium and cobalt release from a metal prosthesis in metal-sensitive patients].
Six rejected stainless steel hip prostheses that had been removed from 15 metal sensitive patient were immersed in different solutions in various containers and maintained at 37 degrees C in complete darkness. Two months later by means of atomic absorption spectrophotometric studies we were able to determine the amount of nickel, chrome and cobalt released in a saline solution. When the chromium oxide passivation coat of the metal prostheses is damaged by orthopaedic surgical implantation procedures the prostheses may rust, releasing metallic ions.
