FIELD: medicine.
SUBSTANCE: repositioning-fixing device consists of a foot, popliteal support, lever, on which a bobbin with a handle is put, joined to an arc, at the ends of which are fastened plates. There is a bolt where the arc is joined to a rope. The injured segment is fastened to the device at two extreme levels, where both levels are rigidly fixed with respect to each other at a given distance along the longitudinal axis of the injured segment. The patient's foot is fixed to the foot of the device, and the proximal section of the shin is held by the popliteal support. Before putting the plaster bandage on at least three levels of the injured segment of the limb, necessary for rigid external fixation of the fracture, posttraumatic oedema is removed first using the repositioning device by applying the arc of the device with plates onto the lower third of the thigh, perpendicular the longitudinal axis of the thigh. By winding the rope onto the bobbin with an arc at its end with reducing plates, pressure is formed on edematous tissue, pressing the posttraumatic oedema. The injured segment is then removed from the device. A plaster bandage is then applied and the segment is then put back onto the device. Closed controlled frame reduction is then done while monitoring with an electrooptical transducer. Measured reducing force is applied using a contractor between two levels of fastening to the loose end of the long bone fragment in a direction opposite its displacement, to its injured segment suitable for anatomical alignment with a reciprocal bone fragment. At the same time at least three rest pads for fixation, which are rigidly joined together after solidification, are formed in the plaster bandage in the plane of possible secondary displacement of long bone fragments.
EFFECT: restoration of limb functions and bone integrity, rigid fixation, prevention of postoperative complications, reduced injuries, cutting on duration of treatment.
