<p>The system has a plate (10) comprising a proximal face (21) and a distal face (22). A pedicle screw (100) is combined with the plate by a through-hole (11) along an axial direction (12) and provided with three consecutive parts (110, 120, 130) integrated with one another. A sleeve (200) comprises an axial transversal orifice (201), and a tapping part (13) is formed nearer to an inlet (211). An integration unit integrates an end (202) of the sleeve with a contact face (139) of a threaded nut (132), so that the through-hole of the sleeve is centered on an axis (138) of a threaded nut.</p> |
