FIELD: medicine; traumatology.
SUBSTANCE: according to the first version, device has transpedicular fixation system screws introduced into vertebra. Heads of screws are connected with longitudinal rods by means of locks. Device also has osseous cement. Any screw is made with at least one cavity fit for pumping osseous cement in. One side of cavity goes to screw's head, and the other its side goes through at least one additional channel to external surface of screw's rod. Plug is disposed inside cavity to prevent pollution of cavity with osseous chips; plug is made for removal. According to the other version, device has transpedicular fixation system screws introduced into vertebra, and osseous cement. Heads of screws are connected with longitudinal rods by means of locks. Any screw is made with at least one cavity fit for pumping osseous cement in. The cavity is made through and it goes to sharpened end of screw's rod. Plug is disposed inside cavity to prevent pollution of cavity with osseous chips; plug is made for removal. Method provides access to back surface of vertebrae subject to treatment and to healthy adjacent vertebra, which are not subject to treatment. Screws of transpedicular fixation system are introduced into those lower and higher vertebrae in such a way that screws goes through leg of vertebrae inside its body. Rest part of transpedicular fixation system is mounted onto heads of screws. Main units of transpedicular fixation system are mounted finally after spinal column is reclined. Both versions can be used for treatment. Osseous cement is pumped into vertebrae's bodies. Broken vertebrae is reclined due to spatial shift of screws relatively axis of longitudinal rods of device.
EFFECT: reliable fixation of vertebrae-moving segment; prevention of screw migration; partial reconstruction of damaged osseous structure.
