Device for setting a spine

A device for setting a spine having damaged vertebrae, said device to be used in conjunction with a spine stabilizing bar and comprising:

• a) an anchoring element to be attached to a vertebra, said anchoring element having:
• 1) a shaft portion having a first end and a second end;
• 2) a ball head located at said first end;
• and
• 3) an anchoring part located at said second end, said anchoring part being selected from the group consisting of a lamina hook and a pedicle screw;
• b) a separate swivel head having a lateral exterior surface and having:
• 1) a first swivel head end in which said ball is located, and can rotate, said first swivel head end having an aperture therein through which said shaft portion extends and can rotate;
• 2) a second swivel head end having screw threading located on said lateral exterior surface thereof;
• and
• 3) a first slot and a second slot located diametrically opposite each other on said lateral exterior surface and for receiving said spine stabilizing bar;
• and
• (c) a cap nut having threading and being suitable for being screwed onto said screw threading of said second end of said swivel head, said cap nut having an inner end which can contact said spine stabilizing bar when said spine stabilizing bar extends through said first slot and said second slot.
