Pedicle screw and multi-axial connector system

A posterior spinal implant system configured to immobilize and stabilize spinal segments as an adjunct to fusion in the thoracic, lumbar, and/or sacral spine. The implant system includes a pedicle screw, a spinal rod; a connector connecting the pedicle screw to the spinal rod. The connector includes a connector body, a polyaxial screw receiver positioned on the connector body and configured to receive the pedicle screw and permit polyaxial orientation of the connector relative to the pedicle screw, a polyaxial rod receiver positioned in the connector body and configured to receive the spinal rod and permit polyaxial orientation of the spinal rod relative to the connector, and a lock installed in the polyaxial rod receiver. The lock is operable to lock the connector relative the pedicle screw, lock the polyaxial rod receiver relative to the connector, and lock the spinal rod relative to the polyaxial rod receiver.
