ROI-A® Anterior Lumbar Cage

1000x1000_insetimage_ROI-A-01

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.

Product Features

1000x1000_insetimage_ROI-A-02

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

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

Optimised 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 3 anchoring plate lengths for an optimised fit and stability in various patient anatomy
  • Optimised implant shape for peripheral coverage of the endplates and strong support on cortical bone
  • The wide graft chamber, optimises the contact between the graft and the vertebral endplates enhancing the quality of the fusion
  • Cage in PEEK-OPTIMA®: This material has an elasticity modulus close to that of bone. The biocompatibility and its mechanical qualities of PEEK-OPTIMA® have been largely recognised 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 optimised fit and stability in various patient anatomy and facilitates the multi-level or hybrid (cage/prosthesis) surgeries
