A tool set for implanting bone screws in a human spine, followed by the implantation of a rod into the bone screws includes end guide tools having flexible back wall flaps that receive opposite ends of the rod and intermediate guide tools that hold the rod in intermediate locations between the end guide tools. Both the end and intermediate guide tools include an attachment structure for operably connecting the guide tool to a bone screw. For bone screw implantation, the end guide tools and intermediate guide tools are assembled with a multi-function installation tool and a bone screw driver. Both the installation tool and driver are coaxial with the guide tool and rotatingly mateable to the guide tool. The multi-function installation tool includes a sleeve that extends substantially about the guide tool providing stability during bone screw installation. The sleeve also operatively functions as a rod pusher that abuts the rod as the sleeve is translated along the guide tool and toward the bone screw. A method utilizing the tool set allows a surgeon to percutaneously implant the bone screws and the rod in the patient. |
