Abstract
Various bone cement guides are disclosed that may connect directly to a fenestrated bone screw or connect to a spinal construct that is coupled to a fenestrated bone screw. In various embodiments, cement guides may include a three-part assembly including a hollow outer sleeve and a hollow inner sleeve with a removable inner rod. In various embodiments, the hollow inner sleeve may be movable between a retracted position and an extended position and in the extended position a distal end of the inner sleeve may splay outward and capture the head portion of a fenestrated bone screw. In other embodiments, a distal end of the outer sleeve may surround and capture tabs of an extended tulip head connector while the inner sleeve couples to an inside surface of the extended tulip head connector.
