ROI-A® is a novel system designed for zero-profile,stand-alone* anterior lumbar interbody fusion. The ROI-A ALIF cage features a large central graft space and is available in a variety of footprints, heights, and angles of lordosis to achieve excellent fit and fill in diverse patient anatomy. The cage accommodates self-guided, self-locking VerteBRIDGE® plating designed to provide stability with no instrumentation protruding anterior of the vertebral bodies.
The self-guided, curved VerteBRIDGE plating is delivered in the plane of the disc through a direct anterior approach, so that the surgery can be achieved with less exposure than may be required to implant contemporary stand-alone systems with screws that must be inserted at oblique and challenging angles. The implant holder facilitates optimization of the anterior-posterior position of the implant, provides soft tissue retraction, and protects vascular structures during insertion of the VerteBRIDGE plating.
