Abstract

A dynamic spinal rod system for semi-restrained holding of the vertebrae with respect to each other in a corrected position while providing varying degrees of vertebral body freedom of movement. A first or “male” component has an enlarged proximal end with a bio-compatible elastic polymer insert through which an anchoring component, such as a pedicle screw, may be placed for attachment, and a cylindrical distal end. A second or “female” component includes a similar enlarged proximal end with a bio-compatible elastic polymer insert through which an anchoring component may be placed for attachment, but has a distal end with a colleted portion into which the distal end of the first component may be inserted and retained to form a joined system. A third “interconnector” component may be used to attach to the proximal end of either of the first two components.
