Abstract
A retractor assembly that includes a base portion in slidable engagement with two or more retractor arms with at least one of the retractor arms releasably securing a retractor blade configured to be anchored to a bone anchor. The retractor blade includes an elongate blade portion with a retractor engagement portion positioned at the proximal end of the elongate blade portion and an anchor mechanism positioned at the distal end of the elongate blade portion. The anchor mechanism includes a first jaw and second jaw configured to engage the bone implant. When closed around or anchored to the bone implant—which may be a shank of a modular screw system—the components of the modular screw are able to be assembled to the shank without adjusting, loosening, or opening the anchor mechanism.
