Abstract
A minimally invasive, percutaneous system that allows for dynamic stabilization of the spine is provided, together with methods of using the system. The system comprises a first bone anchoring member that is anchored in a first vertebra, and a second bone anchoring member that is anchored in a second, adjacent, vertebra. The first and second bone anchoring members include a first head portion and second head portion, respectively, that are designed to hold first and second ends of a flexible, elongated member, or cord. In certain embodiments, the cord is provided with a stiffened, relatively inflexible, end portion that is fixedly attached to the cord and that facilitates threading of the cord through the first and second head portions.
