Abstract
A pedicle screw and rod system for minimally invasive spinal fusion surgery that allows for ease of placement of a fusion rod on the heads of pedicle screws. The system includes extender tubes having a bore extending therethrough. The bore includes a cylindrical portion and a key portion. A slot is formed in the tube along the length of the tube and is open to the bore. The pedicle screws are threaded into the vertebra and the extender tubes are coupled to the heads of the screws so that the slots face each other. The rod is positioned in the slots and is slid down the bores to be coupled to the heads of the pedicle screws. Bolts are slid down the tubes and threaded to the heads of the pedicle screws to secure the rod thereto, and the extender tubes are removed.
