Functioning of the polyaxial plate families
In case of fractures of smaller bones - particularly in case of the comminuted fracture dispositions - the optimal fixing direction can be diverse. In this case, neither the traditional AO-screws, nor the locking screws provide satisfactory result. Instead of these, polyaxial technique can be used.
Medimetal offers two different types of polyaxial plate systems.
As per the functioning method of the first-type polyaxial plate system, lamellas are designed to be located in the holes of the plate. The plates are relatively thin, thus they are suitable for fractures of smaller bones with low biomechanical loading (e.g. in case of hand-, arm- and shoulder surgeries).
Distal volar radius plates
An important member of both polyaxial plate families is the distal radius plate. It provides wide treatment possibilites of radius fractures; the plate is available in right- and in left hand versions.
In case of the polyaxial plate family with lamellas, the right fixing points can be chosen from 9 holes on the plate-head. Kirschner guide wires can facilitate the reposition accuracy and the plate positioning. Beside the 2.7-mm screw - if the bone is porotic - 3.5-mm polyaxial screws can also be used. The product range has distal radius plates with various shaft lengths.
