Astrolabe’s Tibia Proximal 4,5/5,0mm provides a solid, secure and precise locked screws construct associated to the possibility to perform minimally invasive procedures due to it’s insertion guide. This anatomically pre shaped plate was design to attend stabilization of proximal tibia fractures, extra-articular fractures / intra-articular fractures / complete intra-articular fractures / intra-articular fractures associated with coronal fractures / periprosthetic fractures.
