摘要：
The invention relates to medicine, in particular to traumatology and orthopedics, and is designed for osteosynthesis. We have for the first time provides a kit for osteosynthesis, consisting of a bolt with an internal thread and the locking screw with an external thread corresponding to the thread of the bolt and having a head in the form of truncated cones widening distally, characterized in that the conical surfaces on the heads applied external thread. At the ends of the screw bolts and the slots are in the form of polyhedron depth screwdriver, or straight (flat) slot. When using the proposed design may firm connection of bone fragments, the elimination of rotary instability due to screwing conical head screw and the locking screw into the bone. Possible compression of the depth of screwing in screws. Eliminates need for a washer to increase the structural strength of contact with the bone, since the conical head of the locking screw and bolt are screwed directly into bone. Due to the above reduced migration risk retainers, prevented the development of joint contractures, reduced risk of intraoperative complications. Set for osteosynthesis it can be used to treat comminuted, comminuted, fragmented, non-united fractures, pseudoarthrosis, wherein the holding osteosynthesis bone does not depend on the width of the medullary canal through screwing conical head screw and the locking bolt in the cortical bone. In some cases the use of a set of proposed for osteosynthesis in isolation without the intramedullary nail, which leads to a reduction in operative time, reduce her trauma and labor. Reducing the time of the operation and its trauma, reduces length of hospitalization, immobilization disability.Полезная модель относится к медицине, в частности к травматологии и ортопедии, и предназначена для проведения остеосинтеза. Нами впервые предложен набор для остеосинтеза, состоящий из болта с внутренней резьбой и запорного винта с внешней резьбой, соответствующей резьбе бол
