A bone screw tightening device including a screw driver, the screw driver having along an axis of longitudinal extension a device for providing for radial bendability and at a same time preserving torsional stiffness along an axis of longitudinal extension of the screw.
A bone screw tightening device comprising:
- a screw driver,
- wherein the screw driver includes, along an axis of longitudinal extension, at least one device for providing for radial bendability and at a same time preserving torsional stiffness along an axis of longitudinal extension of the bone screw,
- characterized in that the bone screw tightening device further includes a screw extender for removable attachment to a screw head of the bone screw and for holding the bone screw and accommodating the screw driver, and
- in that the at least one device for providing radial bendability is located along the screw driver and located inside the screw extender when the screw extender is attached to the screw head of the bone screw, or at an upper section of the screw driver outside of the screw extender when the screw extender is attached to the screw head of the bone screw.
