Product Overview

The ROI-A® Oblique ALIF cage system is a novel system designed for zero-profile, stand-alone* lumbar interbody fusion. While it shares the features and benefits of the original ROI-A® ALIF cage, which was designed for direct anterior insertion, the ROI-A Oblique cage and VerteBRIDGE® plating can be inserted from a 25° anterolateral angle that may reduce retraction of the great vessels and minimize the associated management of segmental vessels.

It also avoids the neurologic challenges of lateral trans-psoas techniques. These can be key advantages when treating degenerative disease of the lumbar spine, particularly at the L4-L5 level.

* In cases of spondylolisthesis or vertebral instability, the ROI-A implant should be augmented with additional anterior or posterior supplemental fixation.

Features

  • Multiple footprints, lordosis, and heights as well as three plate lengths for optimized fit and stability
  • Optimized cage shape for peripheral coverage of the endplates and strong support on cortical bone
  • Tapered posterior shape to ease insertion
  • Middle beam for strength during surgical placement
  • Large central graft space
  • PEEK-OPTIMA® material for biocompatibility and radiolucency and tantalum markers for verification of cage positioning
  • Sterile packaging for assured product quality and absolute traceability

VerteBRIDGE® Plating Technology

  • Novel stand-alone technology*
  • Zero-profile design with no hardware protruding outside of the vertebral bodies
  • Self-locking plates designed for initial and long-term stability
  • Mini-open technique for intradiscal insertion
  • Adjustable cage placement prior to insertion of the plating
  • Self-guided, curved plates ease insertion
  • Inserter provides protection of vascular structures during placement of the plating

* In cases of spondylolisthesis or vertebral instability, the ROI-A implant should be augmented with additional anterior or posterior supplemental fixation.

Indications for Use (IFU)

The ROI-A Implant System is indicated for intervertebral body fusion of the lumbar spine, from L2 to S1, in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use at either one or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The device system is designed for use with supplemental fixation and with autograft to facilitate fusion.

Note: VerteBRIDGE® Plating is the supplemental fixation designed specifically for the ROI-A cage and can be used in applications where a stand-alone anterior construct is appropriate. Additional supplemental fixation options can be used with the ROI-A cage (with or without VerteBRIDGE Plating) including posterior pedicle systems or additional vertebral plating.
