Dynamic spinal stabilization assemblies, tool set and method

In an insertion tool having an elongated body with an attachment structure at a lower end thereof and secured to an implant receiver, the elongated body preventing splay and rotation with respect to the receiver, the insertion tool comprising:

• a) a laterally opening channel formed in the elongated body and communicating with an interior longitudinal bore of the elongated body, the lateral opening extending upwardly from a lower end of the elongated body, a portion of the opening accommodating a longitudinal connecting member;
• and
• b) a guide and advancement structure disposed on the elongated body interior and spaced from the lower end thereof, the structure rotating mating with a second guide and advancement structure of a longitudinal connecting member reduction tool.

In an insertion tool having an elongated body with attachment structure at a lower end thereof and secured to an implant receiver having a horizontal groove near a top surface thereof, and extending from a flat front surface to a flat back surface of the receiver, the insertion tool comprising:

• a) a laterally opening channel formed in the elongated body and communicating with an interior longitudinal bore of the elongated body, the lateral opening extending upwardly from a lower end of the elongated body, a portion of the opening accommodating a longitudinal connecting member;
• and
• b) a guide and advancement structure disposed on the body interior and spaced from the lower end thereof, the structure rotating mating with a second guide and advancement structure of a longitudinal connecting member reduction tool.
