Embodiments of the disclosure provide a device and system for dynamic spinal stabilization. A collar has an opening for connection to a bone fastener implanted in bony tissue and a slot for receiving a portion of an elongated member. When the elongated member is seated in the slot and a closure member is securely connected to the collar, the collar is capable of selected rotation about the bone fastener to provide dampened motion of the stabilization system.
