“…Although the taper designs used in the head–stem neck junction were varied, a single design head–stem neck junction was used in this study. In any case, all previous studies showed evidence of some fretting and corrosion, as expected from any modular taper connection . We believe that this drawback is partially offset by the various controlled laboratory conditions of the hip simulator test used in this study.…”

“…In any case, all previous studies showed evidence of some fretting and corrosion, as expected from any modular taper connection. 37,38 We believe that this drawback is partially offset by the various controlled laboratory conditions of the hip simulator test used in this study. Furthermore, work will focus on performing hip-simulator wear tests using larger (i.e., 40 or 44 mm) ZTA ceramic and Co-Cr-Mo alloy femoral heads against the Ti-6Al-4V alloy trunnion with a 12/14 mm taper.…”

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.

“…Because of the relatively small sample size (401 revisions for PJI out of 84,894 hips), subgrouping the data set according to head diameter was considered not meaningful. We acknowledge that hips with large metal heads are more at risk of generating a milieu for PJI because of potential taper corrosion, whereas in contrast, ceramic heads can protect the patient from this complication [13,14]. Analysis of bilateral THAs as independent observations is a potential statistical flaw of the study.…”

Periprosthetic Joint Infection in Hip Arthroplasty: Is There an Association Between Infection and Bearing Surface Type?

Background Preliminary studies have raised the question of whether certain prosthetic biomaterials used in total hip arthroplasty (THA) bearings are associated with increased risk of periprosthetic joint infection (PJI). For example, some observational data suggest the risk of PJI is higher with metal-on-metal bearings. However, it is not known whether other bearings-including ceramic bearings or metal-on-polyethylene bearings-may be associated with a higher or lower risk of PJI. Questions/purposes The objective of this study was to use a national arthroplasty registry to assess whether the choice of bearings-metal-on-polyethylene (MoP), ceramic-on-polyethylene (CoP), ceramic-on-ceramic (CoC), or metal-on-metal (MoM)-is associated with differences in the risk of revision for deep infection, either (1) within 6 months or (2) over the entire period of observation, which spanned 15 years. Methods Data from primary THAs were extracted from the New Zealand Joint Registry over a 15-year period. A total of 97,889 hips were available for analysis. Inclusion criterion was degenerative joint disease; exclusion criteria were previous surgery, trauma, and any other diagnosis (12,566 hips). We also excluded a small group of ceramicon-metal THAs (429) with short followup. The median observation period of the selected group of hips (84,894) was 9 years (range, 1-15 years). The mean age of patients was 68 years (SD ± 11 years), and 52% were women. There were 54,409 (64%) MoP,16,503 (19%) CoP, 9051 (11%) CoC, and 4931 (6%) MoM hip arthroplasties. Four hundred one hips were revised for deep infection. A multivariate assessment was carried out including the following risks factors available for analysis: age, sex, operating room type, use of body exhaust suits, THA fixation mode, and surgeon volume.

“…A deeper level of score granularity can provide more details about the severity and spatial distribution of damage. Distribution of the corrosion damage over the distinct zones of tapers has been investigated by a limited number of studies [8,[11][12][13][14][15][16][17][18][19].…”

Metallic taper junctions of modular total hip replacement implants are analysed for corrosion damage using visual scoring based on different granularity levels that span from analysing the taper holistically to dividing the taper into several distinct zones. This study aims to objectively explore the spatial distribution and the severity of corrosion damage onto the surface of metallic stem tapers. An ordinal logistic regression model was developed to find the odds of receiving a higher score at eight distinct zones of 137 retrieved stem tapers. A method to find the order of damage severity across the eight zones is introduced based on an overall test of statistical significance. The findings show that corrosion at the stem tapers occurred more commonly in the distal region in comparison with the proximal region. Also, the medial distal zone was found to possess the most severe corrosion damage among all the studied eight zones.
