There exist an interaction between the implant and the tissue leading to a tissue response expecially in the vicinity of the implanted material.

AND

, Corrosion of a Cobalt-Base Alloy and Its Biological Consequenceslloys are used for fabrication of internal fixation devices. Cobalt based alloys are not widely used in this application due to their high material and fabrication costs and their relative lack of ductility. Such devices are considered to be temporary implants; long term biological effects should not be a factor in their routine use.

The Toxicity of Chromium in the Zero and Trivalent Formhromium in the zero oxidation state are treated to be relatively ‘inert’ and not toxic to man and other species, because of their lower bioavailability (1–6). This paper will summarize the available data from literature on the acute and long-term exposure results of human and experimental studies.

Analysis of Cobalt, Chromium and Nickel in Biological Materials - State of the Artis, 1980; Versieck, 1985). This paper thus summarizes the most important aspects and up to now known facts for reliable analysis of cobalt, chromium and nickel regarded as toxi-cologically significant metals in the use of orthopedic implants (Friberg et al, 1985; Sunderman, 1986).
