“…Laboratory studies of different implant designs with 12/14 tapers have shown a higher grade of corrosion and greater variation in debris particle size with a stainless steel/stainless steel couple compared with a stainless steel/titanium couple. 17 Taper length, taper angle, neck-shaft angle and offset were not investigated. Of note, ‘12’ and ‘14’ refer only to the proximal and distal diameter of the trunnion.…”

“…The primary pathway for corrosion is initiated by oxide depletion caused by fretting although several factors can affect the mechanically assisted crevice corrosion process including mechanical, electrochemical and environmental factors . Dos Santos et al have demonstrated in their in vitro studies that the micromotion between metal alloys can lead to fretting and release of metal debris. Subsequently, metal debris generated in the fretting process can be transported through the contact area of the crevice, leading to a severe chemical and mechanical degradation.…”

Reducing fretting‐initiated crevice corrosion in hip simulator tests using a zirconia‐toughened alumina femoral head

Taper fretting corrosion is considered a potentially limiting factor for total hip arthroplasty longevity. Recently, attention has been focused on new materials for ceramic femoral heads, for example, zirconia-toughened alumina (ZTA), since they have an alternative bearing surface that can improve the wear resistance. Moreover, ceramics have high chemical stability and corrosion resistance. In this study, we evaluated the effects of ZTA and Co-Cr-Mo alloy femoral heads on their taper fretting and/or corrosion characteristics under a controlled hip simulator test. After the test, less fretting and corrosion were observed in the taper surface of the trunnion against the ZTA femoral head than for that against the Co-Cr-Mo alloy femoral head. In addition, corrosion damages were only observed in the lateral-distal taper surface (noncontact area) of the trunnion in the Co-Cr-Mo alloy femoral head group. The ZTA femoral head group also eliminated the potential for Co ion release into the lubricants from taper corrosion, reducing the possibility of adverse local tissue inflammatory responses. In conclusion, ZTA femoral heads showed markedly less fretting corrosion compared to Co-Cr-Mo alloy femoral heads and have a lower potential for metal ion release. © 2017 Wiley Periodicals, Inc.

“…The major strength of this study is the real‐time investigation of the effect of compressive loads on current at the head–trunnion interface in a controlled environment. Most information pertaining to trunnion wear is based on retrieval studies, with only a small number of reports employing controlled electrochemical corrosion chambers . This methodology allows systematic investigation of factors implicated in trunnionosis.…”

Mechanically assisted crevice corrosion (MACC) is a mechanism for trunnion damage in total hip arthroplasties (THAs). Retrieval studies have shown reduced MACC-related damage for ceramic heads compared with cobalt-chromium (CoCr) heads. We propose that ceramic heads demonstrate fretting at higher cyclic compressive loads than CoCr heads on titanium alloy trunnions in a simulated corrosion model. A closed electrochemical chamber was used to measure fretting current onset loads for two modern titanium alloy trunnions (Zimmer 12/14 and Stryker V-40) in which trunnion failure has been reported. Ceramic and CoCr alloy 36 + 0 mm heads were impacted on each trunnion and cyclically loaded at 3 Hz with increasing magnitude from 100 to 3,400 N for 540 cycles. Onset load was the cyclic compressive load at which the slope of the average fretting current increased significantly. A CoCr head with V40 trunnion demonstrated the lowest onset load (1,400 N), while the V40 trunnion with a ceramic head showed the highest onset load (2,200 N). Significant differences occurred in average fretting current between head materials for V40 trunnions (p < 0.001) at loads over 2,000 N. CoCr-12/14 and ceramic-12/14 couples demonstrated similar onset loads (2,000 N). All head-trunnion combinations showed cyclical fretting response to loading at 100 N. Head material composition was observed to increase fretting at the taper junction but the effect was taper geometry dependent. Using ceramic heads may reduce the phenomena of trunnion fretting and corrosion but the effect of both trunnion geometry and metallurgy warrants further investigation. Statement of clinical significance: Trunnion corrosion may occur with titanium alloy stems regardless of the head material used. © 2017 Orthopaedic Research Society.
