Intersomatic cage, clamp for manipulating it and procedure for inserting the intersomatic cage between vertebrae

A system for intervertebral implantation comprising:

• an intersomatic cage which comprises at least one orifice made in the end of a cage lateral area, allowing it to be held by a clamp and positioned, said cage comprising two vertebral facing sides;
• and
• a clamp for manipulating said intersomatic cage, said clamp comprising
• two arms comprising an anterior end and a posterior end, said arms being crossed and hinged to each other at a central area by a hinge, said hinge allowing the arms to slide relative to each other;
• and
• a posterior attachment of said hinged arms that allows a free opening and closing motion and the regulated sliding motion of said arms;
• wherein said anterior end of said clamp arms comprises a shape adapted to at least one orifice used to hold said intersomatic cage;
• wherein said clamp further comprises a copying element that reproduces the shape and attachment rotational orientation of the intersomatic cage held by the clamp, this copying element being rotationally joined at a central area to one of the clamp arms, while hinged to the periphery of the copying element is a cam that is attached to the other clamp arm, reproducing in the copying element a rotation identical to that effected by the intersomatic cage held by the clamp ends.
