The proximal tibial plate is intended for an angularly stable osteosynthesis of the proximal end of the tibia, primarily for the treatment of fractures of the types 41 – A2, A3, B1, C1, C2, C3; based on the Müller classification, and of some storey fractures.

The plate is anatomically shaped in accordance with the lateral side of the shank, it is thus supplied as a left- or right sided version.

There are three screws placed horizontally and three screws placed vertically in the proximal part of the plate. The horizontally placed screws support the tibial plateau; these screws are anatomically slanted by 5°. The vertically placed screws support the horizontal screws.

The shank part of the plate has from seven till nineteen holes - one hole is oval, the rest of them are locking.

 

To these angularly stable plates are used locking screws self-tapping with diameters 5 mm and 5/3,5 mm.

Implants are made of implant steel ISO 58321E or Titanium Ti6Al4V ELI ISO 5832-3.

 

Angularly stable plates

The system is based on the principle of the inner fixator. By means of the tight connection "screw-plate", the angularly stable connection is achieved between the plate and the bone. This transfers part of the weight from the screw-bone connection to the screw-plate connection. Thanks to that it is possible to use the system successfully even in a less quality and an osteoporotic bone.

If the angularly stable plate is used with locking bone screws, the plate and the screws make tight system together. The plate does not have to be pushed against the bone therefore the bone still gets sufficient supply of the blood. Locking bone screws can be introduced monocortically without enfeebling the strength of the configuration or the fracture fixation, because the screws are firmly anchored in the plate.
