FIELD: medicine. SUBSTANCE: method involves fixing injured segment or a segment articulating it below and above the place of injury. Both fixation places are rigidly fixed between each other at given distance along the longitudinal axis of the injured segment. The proximal end of the injured segment or the nearest end of a segment articulating to it at one of the levels to prevent from only forward motion at least in the plane being in perpendicular relation to the said longitudinal axis. The distal end of the injured segment or the nearest end of a segment articulating to it is rigidly fixed in the other point to prevent from only forward motion both along the mentioned longitudinal axis and in the plane being in perpendicular relation to this axis. The main force is applied and the area of its application is rigidly fixed relative to at least two above mentioned fastening levels so that at least three areas for fixing the injured segment not belonging to a single straight line are arisen in every plane of potential bone fragment dislocation below or above the place of injury. Two of them are placed on the corresponding level of injured segment fixation. EFFECT: increased fixation rigidity; biomechanically grounded shape and dimensions of external fixation facilities. 10 cl, 13 tbl
