Abstract

Systems and methods for a guide assembly for introducing a bone anchor to an operative target site. The guide includes an outer sleeve and an inner sleeve. The outer sleeve has a distal anchor engaging end, a proximal end, and a central passage extending from the distal end to the proximal end. The inner sleeve may be situated in the central passage of the outer sleeve. The inner sleeve is movable being between a first position and a second position. The first position permits insertion of the bone anchor in the central passage. The second position releasably fixes the bone anchor to the guide assembly.
