WebPatient 1 is a 76-year-old man who sustained a first dislocation 10 years after primary THA. He was revised after failed nonoperative treatment to a cemented Trident® Osteonics constrained liner (A) that subsequently failed at 2 years with breakage of the locking mechanism.(B).He was rerevised to another constrained liner (C), which also failed at 2 … WebSep 1, 2024 · Indeed, no dissociation of the cemented dual mobility cup or evolution to an aseptic loosening of the retained metal shell was observed in our series. Conversely, a dissociation rate of 5.6% was reported with dual mobility “liner” conventionally used in a modular dual mobility cup system that had been cemented into an existing metal shell [18].
