摘要：
FIELD: medicine.SUBSTANCE: invention relates to traumatology and orthopedics and can be used for minimally invasive surgical treatment of fractures of the anterior pelvic semi-ring bones. Conductor and fixing plates corresponding to the fracture of the left or right half of the anterior pelvic semi-ring are used. Conductor is made in the form of upper and lower tubes, which are fixed in parallel by one ends in the body, wherein the upper tube is nondetachable fixed, and the lower tube is fixed by screws, wherein end-faces of the other ends of both tubes are cut by a plane inclined to their axes at an angle of 45°, internal diameters of the upper and lower tubes are not less than the dimensions of the heads of self-tapping takedown screws of the fixing plate to the bone and the outer diameter of the detachable adapters for a drill or pin with the possibility of their sliding, wherein the other end of the lower tube is in the form of a collet clamp having a movable collet lock covering collet legs and a sectional U-shaped grip, which are divided in two by a plane along the axis of the lower tube and are configured to grip and hold the fixing plate having two oval holes along its axis with an interaxial distance equal to the distance between the axes of the upper and lower tubes, wherein the fixing plate has two blind holes on its proximal portion corresponding to the protrusions formed on the sections of the U-shaped grip, means for separating the collet legs of the U-shaped grip is made in the form of a weakened section of each leg at the point of their bend by means of a transverse curved groove on its outer surface and lateral bevels with through holes, adapted to angularly move the legs from the closed position to an angle α, providing disengagement of the protrusions of U-shaped grip with holes on the fixing plate, wherein an annular groove is formed inside the legs when they are closed in the zone of the U-shaped grip, an elastic element is arranged in the annul
