Methods and devices for providing access to an intervertebral disc using the patient's bony pedicle as an anchoring spot for a pedicle screw that temporarily attaches to an access port are disclosed herein. The disclosed methods and devices can eliminate the need for a surgical table as an anchor, as well as the need for components extending from the table to the port at the access site, thereby unencumbering the surgeon's view and workspace while providing minimally invasive access.
