L-Varlock® Expandable Cage has a large and open framework.
This provides a large footprint of bone graft packed within the cage to contact the vertebral endplates and bone graft packed within the disc space.
When expanding the L-Varlock® Expandable Cage, the expansion pin retracts posterior and can help compress the bone graft up and against vertebral endplates. After expansion, the Bone Graft Funnel can be utilized to pack more autograft into the vertebral disc space.
