Clinical description

NUBIC® is an anterior cervical intervertebral fusion cage developed by SIGNUS for anterior cervical fusion (C3–TH1), implanted using the established Smith–Robinson technique. It belongs to the same family as RABEA®, from which it differs through its curved anatomical surface.

The curved (convex) surface of NUBIC® fits optimally with the endplates of the adjacent vertebral bodies. The open design allows filling with natural bone graft or synthetic substitute; in addition, NUBIC® is also available factory pre-filled with KAINOS® +, simplifying the intraoperative workflow. The serrated teeth characteristic of SIGNUS provide primary stability and a reduced risk of implant migration.

NUBIC® is made of the high-performance medical polymer PEEK-OPTIMA® (radiolucent), with titanium alloy radiographic markers (Ti-6Al-4V) for intra- and postoperative verification and artifact-free MRI imaging. The implant is available in barred (ventral–dorsal) and barless variants, in footprints of 14×13 mm and 17×13 mm. For additional anterior fixation, the TOSCA® or ASCOT® ventral plates can be used.

Indications
  • Degenerative disorders of the cervical disc, at the C3–TH1 level.
  • Disc herniation; mechanical instability; osteochondrosis.
  • Spinal canal stenosis; spondylolisthesis.
  • Pseudarthrosis or failed anterior spondylodesis (fusion).
Key features

Curved anatomical surface

Convex profile that fits optimally with the endplates of the adjacent vertebral bodies.

Pre-filled option

Available factory pre-filled with the KAINOS® + bone substitute, for a simplified surgical workflow.

Open design

Filled with natural bone graft or synthetic substitute and promotes osseointegration.

SIGNUS serrated teeth

High primary stability and a reduced risk of implant migration.

Artifact-free MRI

Radiolucent PEEK-OPTIMA® with titanium markers — optimal postoperative monitoring and safe positioning.

With or without bar

Barred (ventral–dorsal) and barless variants, in two footprints, for adaptation to the anatomy.
