“…However, both wear results were in the same range as the wear rate reported by Wirth et al 25 with conventional UHWMPE. Comparing the results from Wirth et al 25 and Mueller et al, 52 it is evident that cross-linking was the most relevant factor to reduce polyethylene wear. Components studied by Mueller et al 52 exhibited a radial mismatch of 8 mm and 12 mm in A/P and I/S directions, respectively, but both ceramic and metal humeral heads were spherical.…”

“…The UHMWPE wear rate found in the present study was considerably reduced compared with wear rates reported in other shoulder in vitro studies. 14,25,43,[52][53][54][55] Mueller et al 52 reported significantly reduced wear rates for a ceramic humeral head against conventional UHMWPE glenoid compared with a conventional CoCr humeral head against the same glenoid component in an anatomic shoulder wear test. However, both wear results were in the same range as the wear rate reported by Wirth et al 25 with conventional UHWMPE.…”

Background: Glenoid component failures still represent the most common complication in total shoulder arthroplasty. These failures depend on several factors, including ultra-high molecular weight polyethylene (UHMWPE) wear. One reason for UHMWPE wear in total shoulder arthroplasty may be the current use of a spherical prosthetic humeral head against a radially mismatched UHMWPE glenoid component, which leads to reduced glenohumeral translations, glenoid edge loading and high translational forces during shoulder motions. The aim of this study was to assess the in vitro wear of an anatomic total shoulder prosthesis with non-spherical non-conforming bearings with inverted conventional materials. Methods: The wear of a vitamin E-blended UHMWPE non-spherical humeral head articulating against a non-conforming titanium-niobium nitride (TiNbN)-coated metallic glenoid was tested using a joint simulator. The wear test was performed by applying a constant load of 756 N with angular motions and translations. Results: After 2.5 million cycles, the mean wear rate of the humeral head was 0.28 AE standard deviation (SD) 0.45 mg/million cycles. Conclusion: The low wear rate of the vitamin E UHMWPE humeral head supports the use of non-spherical nonconforming bearings with inverted conventional materials in anatomic total shoulder arthroplasty.

“…It can be related to glenoid or humeral component malposition, increased mechanical stress on the glenoid, increased friction between components, or the volume of polyethylene particles generated by the head-polyethylene articulation. 21 Mueller et al 23 used a force-controlled joint simulator to assess the polyethylene wear characteristics influenced by ceramic and metal humeral heads. They showed that the humeral heads made of ceramic material provided a significantly reduced wear rate compared with the metallic humeral heads.…”

Background: In vitro wear studies demonstrate decreased polyethylene wear with a ceramic compared with a metal humeral head. In this in vivo study, we analyzed prospectively collected 5-year data, comparing the outcomes of 2 types of humeral implants. Methods: Sixty-two anatomic total shoulder arthroplasties (TSAs) (59 patients) were performed using the same glenoid component and 2 types of modular humeral implants (metal-head long-stem prosthesis in group A vs. ceramic-head stemless prosthesis in group B). Radiographic analysis for proximal humeral osteolysis and glenoid component radiolucent lines was performed at an average of 5.5 years. Functional outcomes were prospectively evaluated according to the visual analog scale score for pain; satisfaction level; American Shoulder and Elbow Surgeons score; active elevation; Shoulder Pain and Disability Index score; and Disabilities of the Arm, Shoulder and Hand score. Results: There were 39 TSAs in group A (mean age, 68.1 years) and 23 TSAs in group B (mean age, 67 years). Clinical improvement was similar for both groups. Some proximal humeral osteolysis occurred in 56% of all TSAs. Group A showed increased osteolysis compared with group B (72% vs. 30%, P ¼ .005). Glenoid radiolucent lines were far more frequent in group A, and group A showed a direct relationship between the extent of humeral osteolysis and the severity of glenoid radiolucent lines (P < .001). Conclusion: The stemless ceramic-head replacements showed fewer glenoid radiolucent lines and less humeral osteolysis than the long-stem metal-head replacements. In the group with metal-head replacements, correlation was shown between glenoid radiolucent lines and humeral osteolysis.

“…As part of a wear study on shoulder implants, particles were isolated according to an established protocol . Three SEM images were used for this study to compare the Particleanalyzer_HD, the open source software ImageJ (1.49, National Institutes of Health [NIH], Bethesda, MD, USA) and the commercially available Leica QWin (V3 Lite, Wetzlar, Germany) regarding particle number, ECD, AR and R. As recommended in the ASTM the magnification was set to 10,000×, because the majority of the particles had a size between 0.2 and 1.0 μm.…”

Polyethylene wear is one of the major factors influencing the survivorship of joint replacements. Depending on the number, size and morphology of the polyethylene particles, biological responses of the periprosthetic soft tissue in terms of inflammatory processes can occur, leading to loosening of the implant. Various parameters are used to analyze wear particles, which are usually determined by examining scanning electron microscopy (SEM) images with a particle analysis program. In this study, three different software solutions for particle analysis (self‐developed Particleanalyzer_HD, Leica QWin and ImageJ) were compared regarding particle number, size and morphology. These solutions were also compared to the American Society for Testing and Materials (ASTM) F1877‐16 specifications regarding particle morphology. SEM image analysis revealed no differences for the equivalent circle diameter (p = 0.969). However, a significant difference was found for the aspect ratio between the Particleanalyzer_HD and the other two software solutions (p < 0.001) and between Leica QWin and the other two software solutions regarding the roundness (p < 0.001). Only the Particleanalyzer_HD showed an excellent agreement with the ASTM standard for both morphology parameters (intraclass correlation = 1.000). Only the Particleanalyzer_HD calculated the two morphology parameters according to the ASTM standard. A comparison of the particle morphology between different studies is barely possible, as different algorithms for particle analysis are used. It is strongly recommended that the calculation according to the ASTM standard is used to improve future comparability of findings from wear analysis studies. © 2019 Wiley Periodicals, Inc.
