Perfect timing

Edsko refers Gert to Arian. And that timing turns out to be perfect!

When Gert Nijenbanning approached him about an existing osteosynthesis technique that could possibly be technically improved, Ariaan didn’t have
to think twice: the medial neck fracture! The most operated fracture with the most complications…

Rotational stability and volume; the theory


The clinical success

The clinical success
The take home message of this is that when using the Gannet, thanks to respecting the biology of the medial column fracture, a signicant reduction in
the failure rate can be achieved for both undislocated and dislocated femoral column fractures (van Walsum et al. , 2017; Kalsbeek et al, 2016) (). Like the
natural Gannet (the gannet bird), the Gannet implant is extremely streamlined, low in volume and efective.
