METHOD OF CLOSED REDUCTION OF CLAVICLE FRAGMENTS WITH USING TRANSOSSEOUS APPARATUS Russian patent published in 2009 - IPC A61B17/56 

FIELD: medicine; orthopaedics and traumatology.

SUBSTANCE: radiopaque marker is used to determine spatial relationship of fragments. Radiopaque marker is placed by front border of clavicle fracture site and in parallel with the clavicle axis by puncturing skin from thoracic to acromial extremity. It is followed with marked roentgenogram. To control apparatus installation procedure and simultaneous fragment reduction, skin fine wire is used. Skin fine wire is pricked in at first through cross point of proximal fragment axis and perpendicular thereto, equidistant from fragment ends, then through similarly determined point of distal fragment. The wire is considered to be visual reference point reflecting aligned clavicle axis and axis of final position of the apparatus. The wires are delivered, bent and fixed to support bar. If the fragments are not displaced, support bar and apparatus axis correspond to visual reference point. If the fragments are displaced, support bar is installed at the angle to visual reference point. The apparatus is mounted while constantly controlling direction of installed bars relative to that of visual reference point. While nuts of joint bars tightened, fracture is reduced with alignment of apparatus axis along direction of visual reference point. The known length and radiopaque marker position are used. Radiopaque marker is placed within operation as injection needles. Various types of fragment displacement are eliminated simultaneously, thus control roentgenograms are not required in operating theatre.

EFFECT: restored clavicle integrity, controlled and more exact reduction, reduced dimensions of the apparatus, reduced treatment time.
