Abstract

A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion and a second rod portion connected together. The dynamic rod further includes at least a one bias element configured to provide a bias force in response to deflection or translation of the first rod portion relative to the second rod portion. The dynamic rod includes a locking construct which advantageously enables the extension and/or angulation of one rod portion with respect to the other rod portion to be reversibly locked in position. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments of the spine.
