Straight plates angularly stable are used for fixation of femur dyaphysis fractures and for exceptional events of tibia diaphisis. Comparing to the reconstruction plates they are suitable for heavier patients and such fractures where higher load is expected.

To these angularly stable plates are used self-tapping locking screws 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.
