Abstract
A rod anchoring system including a bone anchor and a connector is provided. The connector of the rod anchoring system is configured to be inserted in one orientation and then transitioned to a second orientation to connect the rod to the anchor. The bone anchor includes a detachable extension shaft that acts as a guide for inserting the connector. In use, once the bone anchor has been implanted at a target site on a vertebra, the connector is placed onto the extension shaft and slid along its length in a first orientation to insert the connector. Once the connector is at the implant site, it is transitioned from the first orientation to the second orientation to connect the rod to the anchor.
