Determination of the direction and value of bone fragment rotation displacement in intra- and supracondylar shoulder fractures with the fracture model (experimental study)

The author used the model of intra- and supracondylar shoulder fracture in which all known types of the displacement of proximal fragments, i.e. rotative ones; the ones on the width inwards, outwards and anteriorly, were created. The criteria for rotation displacement estimation were determined. The table for the definition of the value of rotation angle of the proximal shoulder fragment was made up.
