YEREGUI, Santiago et al. Seudotumor infectado en un paciente con artroplastia de cadera con par de fricción metal-metal. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2023, vol.88, n.5, pp.573-580. ISSN 1852-7434.  http://dx.doi.org/https://doi.org/10.15417/issn.1852-7434.2023.88.5.1764.

Total hip arthroplasty (THA) is the main treatment for advanced hip osteoarthritis and its complications include dislocation, infection, aseptic loosening and, to a lesser extent, adverse reactions to metal. Pseudotumor is a rare complication of THA with a metal-on-metal friction couple; its diagnosis and treatment are extremely important to reduce morbidity and mortality. We present the case of a 63-year-old male patient with a 13-year history of THA with a metal-on-metal friction couple who, at the time of consultation, presented a large palpable mass in the right gluteus and paresthesias in the homolateral sciatic nerve. The diagnosis of an infected pseudotumor was reached and treated with hip revision and antibiotic therapy.
