“…Damage of modular head tapers has been assessed using a number of metrics including visual assessment, 10‐12 volume loss measurements, 6,12 mass loss measurements, 13,14 as well as electrochemical assessment of the contacting surfaces 13,14 . Visual assessments are generally qualitative and are based on the subjective judgment of multiple observers who rate the visual or photographic surfaces of the modular connections and provide a score based on the relative quantity and intensity of the observed wear/corrosion on the surfaces 10‐12 . However, scoring methods with different scales and scoring criteria can make it difficult to compare results across different studies.…”

Corrosion and wear are commonly found at the taper-trunnion connection of modular total hip arthroplasty (THA) explanted devices. While metal/metal (M/M) modular taper-trunnion connections exhibit more wear/corrosion than ceramic/metal (C/M) modular taper-trunnion connections, damage is present in both, regardless of material. This study used a combination of assessment techniques including clinical data, visual scoring assessment, optical imaging, profilometry, and x-ray photoelectron microscopy (XPS), to investigate wear mechanisms and damage features at the modular taper-trunnion connection of 10 M/M and 8 C/M explanted THAs. No correlation was found between any demographic variable and corrosion wear and assessment scores. All assessment techniques demonstrated that the stem trunnions had more damage than head tapers for both explant groups and agreed that C/M explants had less corrosion and wear compared to M/M explants. However, visual assessment scores differed between assessment techniques when evaluating the tapers and trunnions within the two groups. Profilometry showed an increase (p <.05) in surface roughness for stem trunnions compared to head tapers for both explant groups. Xray photoelectron spectroscopy performed on deposits from two M/M explants found chromium and molybdenum carbides beneath the surface while chromium sulfate and aged bone mineral were found on the surface suggesting that the debris is a result of corrosion rather than wear. These results indicate that taper-trunnion damage is more prevalent for M/M explants, but C/M explants are still susceptible to damage. More comprehensive analysis of damage is necessary to better understand the origins of taper-trunnion damage.

“…Constructs were disassembled and the taper surfaces of the stems were imaged using the digital mosaic method (DMM), described in detail elsewhere [29]. Briefly, the taper surfaces were sequentially imaged at high magnification along the circumferential and longitudinal directions (HIROX KH-7700, HIROX-USA, Hackensack, NJ) ( Fig.…”

“…In addition, because the components are assembled in vivo, the assembly force and impact technique also affect the performance of the modular connection, its likelihood of loosening, and the potential for adverse events [23][24][25][26][27]. The prevalence of fretting wear has led to the development of standardized scoring systems and advanced imaging techniques that allow for consistent evaluation (grading) of fretting wear and corrosion of taper junctions [12,[28][29][30]. However, despite being well characterized, taper damage remains difficult to predict.…”

“…The goal of this study was to develop a finite element model to predict fretting in THA constructs. Using previously described techniques, the modular surfaces of fatigue tested taper constructs were fully imaged [29]. To avoid observer bias, an automated technique was developed to identify areas of fretting wear on experimental taper connections.…”

Products from fretting wear and corrosion in the taper junction of total hip arthroplasty (THA) devices can lead to adverse local tissue reactions. Predicting damage as a function of design parameters would aid in the development of more robust devices. The objectives of this study were to develop an automated method for identifying areas of fretting wear on THA taper junctions, and to assess the predictive ability of a finite element model to simulate fretting wear in THA taper junctions. THA constructs were fatigue loaded, thus inducing damage on the stem taper. An automated imaging and analysis algorithm quantified fretting wear on the taper surfaces. Specimen-specific finite element models were used to calculate fretting work done (FWD) at the taper junction. Simulated FWD was correlated to imaged fretting wear. Results showed that the automated imaging approach identified fretting wear on the taper surface. Additionally, finite element models showed the greatest predictive ability for tapers exhibiting distal contact. Finite element models predicted an average of 30.3% of imaged fretting wear. With additional validation, the imaging and finite element techniques may be useful to manufacturers and regulators in the development and review of new THA devices.

“…Pacientes com reações adversas por partículas metálicas apresentam dor, formação de pseudotumores nos tecidos moles, instabilidade ou lesões assintomáticas [7]. O aumento da incidência de eventos adversos tem motivado vários autores a investigarem as causas do fretting-corrosion por meio da quantificação ou classificação do dano gerado no implante, bem como tem gerado a busca por soluções alternativas para evitar ou minimizar o fenômeno de fretting-corrosion [8][9][10][11].…”
