An intervertebral disc space distraction system includes a spool core sized to be percutaneously positioned within a portion of a disc space between adjacent vertebral bodies, the spool core having a first diameter. The system further includes an elongate film removably attached to the spool core, wherein the elongate film can be wound around the spool core to increase the first diameter of the spool core.
