A spinal stabilization system includes at least two anchors having a bone attachment portion and a head portion and a flexible assembly coupled to the anchors. The flexible assembly includes a flexible cord, at least two connectors slidably mounted to the flexible cord, and at least one spacer slidably mounted to the cord between adjacent connectors. Each connector couples with a head portion of an anchor. The flexible assembly may be assembled and appropriately adjusted outside the body prior to it being coupled to the anchors. In addition, the connectors may include angled outer surfaces that provide enhanced engagement with the ends of the spacer. A method of stabilizing the spine includes securing anchors to the spine, assembling a flexible assembly outside the body, and coupling the flexible assembly to the anchors. The method may further include providing connectors with angled surfaces to provide enhanced engagement with the spacer.
