Fidji® Lumbar Cage

Product Description

The versatile Fidji lumbar interbody fusion system consists of PEEK cages which are applicable for the posterior, anterior, lateral and anterolateral approach. The implants associate novel material characteristics with anatomic shapes and are available in various designs and sizes.


  • Rounded tip for easier insertion
  • Convex shape to better conform to the vertebral endplates
  • Three lordotic options (0, 4°and 8°)
  • Autostatic teeth help prevent backing out of the cage
  • Large bone graft area
  • Optional fin in anterior, anterolateral and lateral versions to help resist migration
  • The Fidji lumbar cages are designed for segments L1 to S1


Uni- or multilevel interbody fusion in case of:

  • degenerative instabilities,
  • post-discectomy syndrome,
  • spondylolisthesis,
  • posttraumatic instabilities,
  • previous spinal surgery.

These and any other indications are subject to the judgment of the surgeon, taking into account the specific clinical, biological, and biomechanical setting of each patient.
