RABEA by SIGNUS – gold standard in anterior cervical fusion

Promotional feature



SIGNUS developed the first plan-parallel fusion cage worldwide. RABEA® received CE approval in 1996 and is, more than 25 years later, still gold standard in anterior cervical fusion. With its proven design, RABEA® is simple and efficient.

The disc replacement implants were developed for the specific requirements of anterior cervical vertebral fusion (C3 – TH1). The implant ranges are available in various designs, footprints, heights and angles to enable adaptation to different patient anatomies.

RABEA® is either available as solid titanium (Ti-6Al-4V) or as high-‑performance PEEK‑ OPTIMA®. For successful osseointegration the open design permits the cage to be packed with natural or synthetic bone graft substitute such as KAINOS® Inject. The large selection of implants provides for a high degree of intraoperative flexibility and ensures restoration of the intervertebral space. For RABEA® there are disc replacements available in a 5° lordotic angle as well as plan-parallel implants.
