[The structure of distracting-compressing stabilizers Dynastab DK intended for functional treatment of articular fractures].
The structure of the distracting-compressing stabilizers Dynastab DK intended for functional treatment of transarticular fractures is described. The stabilizers realize the idea of functional treatment of fractures outside the hospital bed making possible free moving around of the patient during the treatment. This has been made possible owing to building-in of a mechanical articulation imitating the physiological movement in the injured joint. The articulation in the stabilizer reduces also the load on the joint. In the stabilizers for the treatment of such fractures of the elbow joint and ankle joint the articulations are monoaxial (hinge-like). In the stabilizer for the treatment of the radiocarpal joint this is a hinge articulation making possible flexion in sagittal plane. In the stabilizer for knee fractures the movements in the injured joint are taken over by a mechanical articulation of special structure. The distracting-compressing action of the Dynastab DK stabilizers for the treatment of transarticular fractures is realized by the tension screw mechanism e.g. in the stabilizer for the treatment of knee joint fractures. In the case of stabilizers for ankle joint, radiocarpal joint and elbow joint this tension is provided by calibrated compressing springs.
