Devices and methods include a multi-axial anchor assembly engageable to a vertebra and a connecting element positionable through a receiver of the anchor assembly. The anchor assembly includes a flexible member between the receiver and an anchor member of the anchor assembly, thereby providing a flexible joint in the anchor assembly for allowing limited movement after primary multi-axial capability between the receiver and the anchor member has been arrested.
