The retractor device is designed to be coupled to a pedicle screw and then to have opposed arms of the retractor spread apart to open the wound proximally. The retractor is removed by separating the opposed blades to allow the retractor portions to be pulled out of the wound. The retractor is intended to be made of a flexible metal 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.
