Testimonials from early users

PYTHEAS ODYSSEY is a valuable aid to pedicle implant placement, whether for simple lumbar procedures or more complex ones.

The device is simple to use and does not fundamentally alter the usual surgical procedure, unlike navigation systems which require sometimes complex triangulation and the presence of intraoperative 3D imaging.“

Dr H. GIORGI, Institut Méditerranéen du Dos (IMED), France

“ I use the PYTHEAS ODYSSEY system to help position my implants in deformity surgery and complex lumbar surgery.  

It's a simple, effective and reliable device, offering a very good alternative to a navigation system.

Dr A. FAURE, Institut Méditerranéen du Dos (IMED), France

“ Having accompanied the development of PYTHEAS NAVIGATION from the innovative idea of its designer to its CE marking and its launch on the market, I have the pleasure of now using a successful product which, in my opinion, meets the expectations of a surgeon : a reliable, simple, useful tool, easy to use for the practitioner and their assistants. PYTHEAS solution is a real 3D compass guiding the surgeon's tools to a place that is difficult to visualize. 

You can operate without it, but having it at your disposal transforms pedicle targeting, particularly in spinal deformities, into a relatively safe procedure and allows you to concentrate on other issues (balance, quality of reduction, etc.) 

Dr D. AFONSO, Hopital Saint Joseph (Marseille), France
