Item type:Publication, Access status: with files , Head taper corrosion causing head bottoming out and consecutive gross stem taper failure in total hip arthroplasty(Elsevier, 2018-07-24); ; ; ; Taper corrosion in total hip arthroplasty for bearings with metal heads against polyethylene has developed from an anecdotal observation to a clinical problem. Increased taper wear and even gross taper failure have been reported for one particular design. It is hypothesized that corrosion of the female head taper results in taper widening, allowing the cobalt-chromium head to turn on the stem and wear down the softer titanium alloy by abrasive wear, ultimately causing failure. The purpose of this study is to investigate the time course of this process and the general role of taper dimensions and material in this problem.Publicationtype: Journal ArticleScopus© Citations 42 308 825 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Fretting-Korrosion modularer Hüftendoprothesen(2017); Early failure of total hip replacements can be caused by the release of wear products from modular junctions due to fretting-corrosion. The aim was to identify design factors that make the analyzed tapers susceptible to wear and corrosion. A quantitative analysis of wear from circular and flat taper designs for a mixed metal coupling (CoCr-TMZF) was performed. Based on the reconstruction of explanted taper geometries, individual engagement properties are determined, providing an estimate of the contact situation at the taper interface in-vivo. This mechanical approach gave explanations of the arrangement of local wear phenomena at the taper interface.Publicationtype: Doctoral Thesis718 490 - Some of the metrics are blocked by yourconsent settings
