“…This leaves the cobalt (Co 2+ ), known to be extremely soluble at the electrode potential and pH found at the interface, to migrate and leave the interface due to an electrical potential established across the interface due to the separation of anodic and cathodic areas. This has also been observed in experimental simulations complimenting clinical literature (Bryant et al, 2013a;Bryant et al, 2013b).…”

“…Such factors will control the way proteins will orientate and interact with the metallic surface. In a previous in-vitro study (Bryant et al, 2013b), comparable tribo-films were seen to form on both the femoral stem as well as the counterpart bone cement. Although these studies were conducted in the absence of proteins, particle morphology and film chemistries were consistent with the retrieval products (compacted crystalline metallic Cr2O3debris in the absence of the surrounding organic debris).…”

“…Full details of the experimental arrangement and electrochemical method have been reported elsewhere [16,15]. In brief, cemented femoral stems were orientated at 9 and 10˚ flexion and extension, respectively, and subjected to a compressive sinusoidal load (0.3-2.3 kN) at 1 Hz.…”

“…Although the wear mechanisms acting at the stem-cement interface are fairly well accepted, they tend to be lesser known and assumed when compared to bearing or taper interfaces. Currently only a few studies exist investigating the role of fretting-corrosion and the influence of system variables at the stem-cement interface [8,14,11,15]. Recently the authors have presented systematic work outlining the tribocorrosion mechanisms [15,13] and role of system variables such as cement type [16,17] and mixed metal couples [18] on the overall degradation of cemented femoral stems.…”

The use of cemented femoral stems is common practice worldwide with strong clinical data supporting their use.Over the years, different surface processing techniques have been employed to enhance the performance of the stem-cement interface. As a result different clinical outcomes and visual presentation at revision has been observed. Whilst research has focussed on increasing adhesion and better load bearing capacity, the effects of surface processing on the degradation of cemented femoral stems has not been investigated. The aims of this study was to investigate the effects of surface processing on the subsurface microstructure, surface chemistry and tribocorrosion degradation mechanisms of cemented tapered femoral stems subjected to polishing and blasting (Vaquasheen) processes. Cemented femoral stems were orientated and loaded according to for 500,000 cycles in 0.9% NaCl at 37 ˚C. A three-electrode electrochemical cell was integrated into the mechanical test to facilitate in-situ corrosion measurements. The severity and mechanism of damaged were assessed scanning and transmission electron microscopy, X-ray photoelectron spectrometry, solution mass spectrometry and white light interferometry. Surface processing was seen to drastically influence the level of corrosion within the interface with polished surfaces demonstrating the highest levels of corrosion. Surface analysis consistently demonstrated the presence of a SiO2 layer on the vaquasheened stems thought to originate from the glass bead blast matrix. This resulted in lower levels of corrosion both under static and tribocorrosion assessment. In conclusion, blasted surfaces resulted in lower wear induced corrosion when compared to the polished surfaces. However the total metallic ion levels did not follow the same trend. This is thought to be due to the formation of metallic debris and dissolution of debris due to abrasion of the femoral stems.

The occurrence of damage on polished femoral stems has been widely reported in the literature, and bone cement has been implicated in a tribocorrosive failure process. However, the mechanisms of cement‐mediated damage and the impact of cement formulation on this process are not well understood. In this study, 13 Zimmer CPT polished femoral stems, and the corresponding cement specimens were retrieved at revision surgery and analyzed using high‐resolution imaging techniques. Surface damage attributed to tribocorrosion was observed on all stems. Corrosion product, in the form of black flaky surface debris, was observed on the surface of cement specimens; both energy‐dispersive X‐ray spectroscopy and inductively coupled plasma mass spectrometry(ICP‐MS) confirmed the presence of cobalt and chromium, with the ICP‐MS showing much higher levels of Cr compared to Co when compared to the original stem material. Agglomerates of ZrO2 radiopacifier were also identified on the cement surface and, in some cases, showed evidence of abrasive wear; the size of these particles correlated well with elliptical pitting evident on the surfaces of the corresponding stems. This evidence supports the hypothesis that agglomerates of hard radiopacifier particles within the cement may induce a wear‐dominated tribocorrosive interaction at the stem–cement interface that damages the surface of polished CoCr femoral stems. © 2016 Wiley Periodicals, Inc.
