The PRESIDIO Anterior Lumbar Fixation System is designed to take away the requirement for posterior stabilization with anterior lumbar interbody fusions. The plate has a low profile design that gives it a rigid and stable construction without disturbing nearby vasculature. The plate also has a graft window that permits visualization during anterior lumbar interbody placement. Its key features include plates that have different lengths for 1 level procedures and bones screws with fast turn thread design with variable angle configuration. The plate also has features that avoid plate misalignment.
