Abstract
Instability following primary and revision hip arthroplasty does occur. Constrained acetabular devices are one way of treating this. We present dislocation at the bipolar interface of a Trident Tripolar Constrained Device and use this case to remind surgeons that closed reduction of this device is not possible.
Résumé
Une instabilité à la suite d’une arthroplastie de hanche de première intention ou de révision peut survenir. Les cupules cotyloïdiennes contraintes sontune des voies pour prévenir cette complication. Nous rapportons un cas de luxation à l’interface bipolaire d’une cupule cotyloïdienne contrainte de type Trident Tripolaire et nous appuyons sur ce cas pour prévenir les chirurgiens que la réduction à ciel fermé de cette cupule n’est pas possible.
