Se debe tener una alta sospecha clínica en pacientes con dolor tras una función protésica adecuada y que presentan un chirrido audible. Radiográficamente puede pasar desapercibida, ya que no suele ser tan apreciable como cuando hay una luxación protésica. Sus principales causas asociadas son el diseño del componente, la mala posición debido a una inclinación y anteversión incorrectas, y el pinzamiento del componente. El diseño modular del componente acetabular inevitablemente es un riesgo para este tipo de evento, por lo que siempre que se utilice un liner acetabular se debe comprobar que esté bien anclado a la copa acetabular durante su colocación y verificar que no haya tejido interpuesto antes de ser impactado, además de una colocación correcta de componentes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Dissociation of the acetabular liner is a rare complication after a total hip arthroplasty. However, when it happens, the integrity and functionality of the prosthesis is at risk. The clinician must be aware of this possible complication in patients that report a sudden onset of pain in a previously functional prosthesis, followed by an audible squeaking. Radiographs may be unnoticed because the changes usually not as remarkable as in a THA dislocation. The most important causes are the component design, malposition and impingement. A modular component is inevitably a risk for these events, and one always should check that the locking mechanism works and avoid interposed tissue before its impaction, and a correct anteversion and inclination of the acetabular component.]]></p></abstract>
