Product Overview

ROI-A® is an ALIF cage with an innovative anchoring system avoiding the use of anterior plate or screws.

Its "zero-profile" design ensures that no hardware will protrude anteriorly to the vertebral bodies.

Insertion of the cage and the VerteBRIDGE® is done in the axis of the disc, for an anterior mini-open technique.

The ROI-A oblique implant has the same characteristics than the
ROI-A median while offering an antero-lateral approach at 25° in order to minimize the blood vessels retraction when treating the high lumbar levels.

Features

ROI-A Oblique

Designed for patient safety

  • Innovative anchoring technology made of Titanium alloy (Ti6Al4V) avoiding the use of anterior plates or screws.
  • "Zero-profile" design with no hardware protruding anterior of the vertebral bodies.
  • The curved self-locking anchoring plate incorporating a central self-retaining clip, secures the anchoring system and the cage inside the intersomatic space.
  • Implant-holder provides protection of vascular structures during anchoring plate placement.

ROI-A Oblique

ROI-A Oblique

A safe and direct insertion

  • Anterior mini-open technique for insertion in the transverse plane.
  • Tapered posterior shape to ease insertion.
  • Middle beam for strength during surgical placement.
  • Millimetric adjustment of the cage-holder ensures optimal positioning of the cage prior to half anchoring plate insertion.
  • Self-guided, curved anchoring plates keep the implant and bone graft in compression.
  • Implanted with just 2 instruments and 2 easy steps, reliable, fast and reproducible insertion.
  • Tantalum markers for verification of implant positioning per-operatively and post-operative follow-up.
ROI-A Oblique

Optimized stability and fusion

  • The ROI-A cage has a teethed surface and by a wide range of multiple footprints, lordosis and heights as well as three anchoring plate lenghts for an optimized fit and stability in various patient anatomy.
  • Optimized implant shape for peripheral coverage of the endplates and strong support on cortical bone.
  • The wide graft chamber, optimizes the contact between the graft and the vertebral endplates enhancing the quality of the fusion.
  • Cage en PEEK-OPTIMA®: this material has an elasticity modulus close to that of bone. The bio-compatibility and its mechanical qualities of PEEK-OPTIMA® have now been largely recognized in interbody application. The fusion can be assessed and controlled overtime due to the radiolucency of the cage.
 

Comprehensive selection to match patient anatomy

  • The ROI-A wide range of footprints, lordosis and heights allows to obtain an optimized fit and stability in various patient anatomy and facilitates the multi-level or hybrid (cage/prosthesis) surgeries.
