Hey there:
He's using a different system than what he uses in Switzerland. It's called the
CoLigne Ostapek. I haven't had a lot of time to look it up, but it does use articulating screw heads, a major factor when it comes to long-term screw retention, and apparently the highest-tech carbon technology. Their website does allow for translation. Upon re-visit, here's a
more specific link about the stabilization system, and finally, information detailing the technology can be found in
this detailed product release. I hope this helps!
