Proximal ulnar plates are intended for osteosynthesis in articular and extra-articular fractures. The aim of osteosynthesis is the reconstruction of the articular surface, stable fixation of fragments, and restoration of ulnar length and angle.
The plates are made of titanium alloy Ti6Al4V (ISO 5832-3) or steel alloy 1.4441 (ISO 5832-1).
The plates are equipped with two kinds of holes for the screws:
Oval hole is used for attaching the plate to the bone and possibly the correction of its position to the distal end of the elbow bone (ulna). Only diameter 3.5 mm cortical screws with diameter 6 mm head may be used for this hole.
Locking openings are provided for locking screws diameter 3.5 and diameter 3.5/2.7 mm with diameter 5 mm head. You can use diameter 1.5 mm K-wires for temporary fixation of the plate.
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.
