Metal in Total Hip Arthroplasty: Wear Particles, Biology, and Diagnosis

Abstract: Total hip arthroplasty (THA) has been performed for nearly 50 years. Between 2006 and 2012, more than 600,000 metal-on-metal THA procedures were performed in the United States. This article reviews the production of metal wear debris in a metal-on-metal articulation and the interaction of cobalt and chromium ions that ultimately led to a dramatic decline in the use of metalon-metal THA articulations. Additionally, the article reviews mechanisms of metal wear, the biologic reaction to cobalt and chromium ions, … Show more

“…Resurfacing and total MoM hip arthroplasties produce abundant cobalt-chromium (Co-Cr)-containing metal wear debris in both particulate and soluble forms. In periprosthetic tissue, particulate Co-Cr wear debris is phagocytosed by macrophages and macrophage polykaryons (giant cells) as part of the innate immune response to foreign material [3, 58]. Co-Cr particles and Co and Cr ions are cytotoxic and can elicit an adaptive cell-mediated immune response; as a consequence, there is marked necrosis and inflammation in periprosthetic tissues and MoM arthroplasties have been associated with early implant failure and pseudotumour formation [510].…”

“…From these results, it was suggested that repeat imaging should be performed at least annually, and the usefulness of results over a year old severely questioned. Furthermore, as cyst progression has not been observed earlier than 6 months postoperatively, annual followup has been recommended in other studies 43. In addition, although some work has begun to assess the time-course of growth of the pseudotumors, there is a large discrepancy between results.…”

“…Several studies involving different types of implant-derived wear products (ions/particles) and their biological effects on living cells have been conducted recently (Alves et al, 2013(Alves et al, , 2015Amanatullah et al, 2016;Bitar and Parvizi, 2015;Cvijović-Alagić et al, 2016;Konttinen and Pajarinen, 2013;Ribeiro et al, 2016;Sukur et al, 2016;Vasconcelos et al, 2016). Previously, Hallab et al (2001) already studied the metal concentrations in blood serum and implant-surrounding tissues after revision surgeries in human patients with orthopedic devices based on Ti-6Al-4V alloy (and others).…”

“…As previously mentioned, wear particles also may trigger increased production of proinflammatory cytokines by different cells in vivo, activating osteoclasts, increasing bone resorption by osteolysis, leading to different adverse tissue reactions, such as metallosis, particle disease and, ultimately, the implant loosening (Amanatullah et al, 2016;Bitar and Parvizi, 2015;Hallab and Jacobs, 2017;Landgraeber et al, 2014;Sukur et al, 2016;Veronesi et al, 2017). Important aspects addressed in these studies are the physicochemical characteristics of the wear particles used, such as, size, morphology, and chemical composition, which will strongly influence their biological fate inside a living organism (Madejczyk et al, 2015;Ribeiro et al, 2016;Sansone et al, 2013;Vasconcelos et al, 2016;Zhang et al, 2017).…”
