ROI® Graft and Fusion
The quality and contact surface of the graft are essential for the success of arthrodeses.

A vast grafting area and a single fusion chamber
• The ROI concept favors grafting by creating a single fusion chamber.
• ROI Implants are shaped with an opening allowing them to be thicker without reducing the grafting surface.
• Free contact between the grafts within the open implants allows a “one-and-only” fusion block.

The ROI PVBR enables vascularization from one vertebra to the other over the largest possible area.
