Abstract
A spinal stabilization system includes a pair of vertebral anchors and a flexible construct extending between the anchors to provide dynamic stabilization of the spine. The flexible construct includes first and second spring arms coupled to the anchors at first ends thereof and second ends coupled at a joint. The spring arms are capable of flexing toward and away from each other during movement of the spine. The system may include a biasing member for biasing movement of the spring arms toward and/or away from each other. The system may further include an adjustment feature that allows the distraction to be adjusted in situ. The stiffness characteristic of each of the spring arms may be selectively adjusted to meet the specific application. A method of stabilizing a spine includes securing anchors to selected vertebrae and coupling the flexible construct to the anchors through a top loading procedure. The flexible construct may be coupled so that a rotational axis of the flexible construct is anterior of a head portion of the anchors.
