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.
