Methods and devices are provided for anchoring spinal rods. In general, devices are provided that can be configured to attach to a rib of a patient. In some embodiments, a device configured to attach to a rib of a patient to facilitate anchoring of a spinal rod coupled thereto can include first and second connectors each configured to attach to a rib of a patient. The first and second connectors can be independent elements and can be configured to be movable relative to one another. A spinal rod can be configured to couple to the device, to move relative to the first and second connectors and the rib after the first and second connectors have been connected to the rib, and to attach to a second device attached to another portion of the patients anatomy, thereby securing the spinal rod in a fixed position to facilitate treatment.
