Abstract
A screw tower that is a single-use instrument that attaches to existing screws but remains open along a rod slot to allow for screws to intermesh and prevent interference of adjacent screws during screw and rod insertion. The screw tower interfaces with existing features of the screws to facilitate screw insertion, rod insertion, rod reduction, and locking cap insertion in a percutaneous approach. The tower is broken in half and removed from patient to end with a completed construct.
