COMPRESSION AND DISTRACTION APPARATUS OF EXTERNAL FIXATION FOR OSTEOSYNTHESIS IN TREATING FOOT BONES AND BRUSH

摘要

The compression-distraction apparatus for external fixation for the osteosynthesis for the treatment of foot bones and hand comprises two strips with holes, first and second, are interconnected to be movable apart by means of a lead screw with a head, as well as bone screws, attached to brackets holes , and they are further arranged in parallel to each other and are at a certain distance from each other by two guide rods, one end of which is rigidly fixed to the first bar and the second ends thereof mounted for free movement in the longitudinal holes made in the second strip, with the lead screw made with single thread disposed between said bars and fixing one end rotatably mounted in the first bracket, a threaded part mounted in a longitudinal threaded hole made in the second strip, and the head of the screw shaft is located outside the free ends of the guide rods, that is cantilevered with the slotted holes of the second strap
