Crevice corrosion in orthopedic implant metals

Abstract

SummaryStudies of orthopedic implant alloys in crevice configuration suggest that cobalt-chromium alloys such as Haynes-Stellite 25 are the best choice for multicomponent implants. It is also shown that severe crevice attack may result from use of mixed metals.

Modular Taper Junction Corrosion and Failure: How to Approach a Recalled Total Hip Arthroplasty Implant

“…If the oxide layer in this crevice environment is damaged, there may not be sufficient oxygen or oxygen-containing species available to repassivate the surface. The aqueous microenvironment in the crevice may then, under certain situations, become acidic (pH 1 to 3), leading to further damage to the passivation layer and corrosion [11,13,15].…”

“…In the intervening decades, multiple avenues of research have elucidated the chemistry of corrosion, with the most common modes of concern to orthopaedic surgeons including galvanic corrosion [7,8], fretting corrosion [9][10][11][12], crevice corrosion [13][14][15], pitting corrosion [16], and intergranular corrosion [17] (Table 1).…”

Functionally graded bioactive coatings: Reproducibility and stability of the coating under cell culture conditions

“…Bioinert metal alloys (Ti6Al4V, Co-Cr and others) have been used as implant materials because they can support loads while provoking only minor reactions in the body [1][2][3][4][5]. The degree of the reactions can vary depending not only on intrinsic properties of bioinert materials but also on the site of implantation, degree of trauma and implant fit [6,7].…”

“…Such particles can lead to an inflammatory tissue reaction with the formation of necrosis, granulation and fibrous tissue. Most research on these aspects goes back to the seventies and eighties of the last century [8,9].…”
