VALDEZ, Sebastián E. Cotilos de doble movilidad: Uso para la revisión femoral aislada de prótesis de cadera con fricción metal/metal con cabezas grandes. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2019, vol.84, n.1, pp.55-62. ISSN 1852-7434.

Large head metal on metal hip arthroplasty revision has a significant complication rate, mainly related to the removal of the acetabular component, as well as to the friction pair used. In some cases, an isolated femoral revision can be made, sparing the acetabular cup and, thus, decreasing surgical morbidity. This paper discusses a case successfully treated with a dual mobility acetabular cup in a patient with a resurfacing hip replacement and a pseudotumor that caused pain and instability. Mastering this surgical approach allows hip surgeons to solve complex problems in a simple and safe manner, and with a low complication rate.
