Diagnostics of rotational displacements for tibial bone fractures

Purpose. To work out an effective and simple technique for determination of the size and direction of rotational displacements by two standard x-ray views based on the regularities of changes in linear parameters of fragments for different direction and angles of their rotation around their own axis. Material and Methods. The technique for rotational displacement diagnostics for fractures developed on the basis of leg bone tomogram analysis. Results. The simplicity and accuracy of the proposed technique proved by clinical examples. Conclusion. The use of the technique proposed allows to facilitate the diagnostics and elimination of fragment rotational displacements in case of leg bone fractures to a great extent.
