SYSTEMS AND METHODS FOR DELIVERING BONE CEMENT TO A BONE ANCHOR

摘要

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.
