A system for delivering bone cement to a bone anchor includes an anchor connection instrument for releasably connecting to a proximal end of the bone anchor. The anchor connection instrument includes a first member coupled to an opposed second member. The first member and the second member have a distal end configured to releasably connect to the proximal end of the bone anchor. The first member is movable between a release position to facilitate release of the anchor connection instrument from the proximal end of the bone anchor and a connect position in which the first member and the second member connect to the proximal end of the bone anchor. A cement delivery tube is positionable in the passage between the first member and the second member of the anchor connection instrument. A bone cement delivery system is coupled to the tube.

L'invention concerne un système d'apport de ciment osseux à une ancre osseuse, qui comprend un instrument de connexion à l'ancre pour la connexion réversible à une extrémité proximale de l'ancre osseuse. L'instrument de connexion à l'ancre comprend un premier élément couplé à un deuxième élément opposé. Le premier élément et le deuxième élément ont une extrémité distale conçue pour la connexion réversible à l'extrémité proximale de l'ancre osseuse. Le premier élément est mobile entre une position de libération visant à faciliter la libération de l'instrument de connexion à l'ancre de l'extrémité proximale de l'ancre osseuse et une position connectée dans laquelle le premier élément et le deuxième élément se connectent à l'extrémité proximale de l'ancre osseuse. Un tube d'apport de ciment peut être positionné dans le passage entre le premier élément et le deuxième élément de l'instrument de connexion à l'ancre. Un système d'apport de ciment est couplé au tube.
