摘要：
The invention relates to medical engineering and can be used in traumatology, orthopedics and neurosurgery for performing percutaneous spinal stabilizing operations in low bone mineral density on a background of systemic osteoporosis, trauma, metastatic disease and spinal deformities. Proposed transpedicular screw comprises a head with an internal thread and the threaded portion, the inner longitudinal bore for introducing bone cement into the vertebral body, side openings formed in the threaded portion and a cavity connecting the inner longitudinal channel with an outer surface of the threaded portion of the screw. It proposed to the threaded part of the screw thread to perform with raznoshagovoy. Wherein the thread pitch of the screw top should be smaller than the pitch of the screw thread bottom. Side holes are made in the part of the screw with a large slicing step, while the screw head is further provided with flanges breaking off from the titanium alloy length of 10-12 cm. The internal thread of the screw head is associated with an internal thread of the flanges, the length of at least 1/4 of their length and the end portion of the flange is provided with locking ridges adapted to be detachably. Ease of use and user-friendly design of the utility model allows you to quickly and efficiently apply it in injuries and diseases of the spine, to perform both open and percutaneous stabilizing spinal surgery without the use of additional structures in the face of declining fixation properties of bone.Полезная модель относится к медицинской технике и может быть использована в травматологии, ортопедии и нейрохирургии для выполнения чрезкожных стабилизирующих операций на позвоночнике в условиях недостаточной минеральной плотности костной ткани на фоне системного остеопороза, при травмах, метастатическом поражении и при деформациях позвоночника. Предлагаемый транспедикулярный винт содержит головку с внутренней резьбой и резьбовую часть, внутренний продольный канал для вве
