ROI® Radiolucency and Safety
The use of PEEKOptima ®, an advanced polymeric biomaterial with an extensive track record in fusion applications is ideal for follow-up and control.

Radiolucency and consistency
• The biocompatibility and mechanical qualities of PEEK-Optima® are largely recognized in fusion applications.
• PEEK-Optima® has an elasticity close to that of bone so that there is no graft weight-bearing problem. There is consequently, a biomechanical consistency between two spine segments, the fusion of which can be assessed radiographically.

Safety
• The MC+® and ROI PVBR are implanted according to a reproducible operating technique.
• The serrated profile of the implant ensures their self-retaining properties, until fusion takes place.

Tantalum markers facilitate intraoperative positioning and follow-up of the PBVR.

ROI and MC+® instrumentation was designed by and for spine surgeons.
