FIELD : medicine. SUBSTANCE : invention relates to medicine. System for plate osteosynthesis consists of a plate with threaded holes, mating with a screw thread screw with a head, which between the head and the screw thread has a thread-free area, the length of which corresponds to the length of the screw thread of the threaded hole of the plate. Additionally place the threaded section between the screw head and the area free from thread, whose length corresponds to the length of the screw thread in the hole of the plate, and the diameter of the section free from the thread is equal to the internal diameter of the screw thread. EFFECT : invention ensures the achievement of a reliable mounting of the bone plate, the creation of convenience when installing the plate osteosynthesis systems with the achievement of the required rigidity of fixation. 1 cl, 3 dwg
