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.
