A device, system and method for orthopedic spine surgery using a novel screw-based retractor, disclosed herein, that allows for access to the spine through a minimally or less invasive approach. The retractor device is designed as a co-molded part of the tulip of a pedicle screw assembly with opposed arms of the retractor spread apart to open the wound proximally. The arms are removed by separating the arms from the tulip and removing them from the incision. The retractor device is intended to be made of a relatively stiff material, sterile packaged and disposable after one use. A system and method for using the retractor and performing a minimally invasive spine surgical procedure are also disclosed.
