摘要

Including pedicle screw (1), the upper part (2), and a threaded hollow hexagonal platform (3), (4), a cylindrical passage extending threaded worm holes (5), (6), a flow channel for insertion of a metal wire initerno Guide (7), the axes of the torque (8), nozzles (9) the cannula (10) for the inse Ru00e7u00e3o cement via syringe injection (11) in a bone (12), perforation.You will receive a parafus; the final (13); said grouting system provides the steps of: United first drilling the bone (a) enlargement of the cavity - (b), cleaning the cavity (c); conformation of internal thread in the cavity (d), the insertion of the pedicle screw (1) the wire guide met u00e1lico (7) - (E), docking of the cannula (10) - (f).Insertion of the cannula and cement internal channel of the pedicle screw - (g) in the bone cavity, via the injection syringe (11), withdrawal of the pedicle screw (H) and placing the final screw (13) - (I).
