Abstract
An assembly for use in spinal stabilization procedures having first and second bone anchor assemblies. Embodiments of the first bone anchor assembly may include an anchor, a poly-axial head, including a cavity, mated with the anchor such that the anchor is movable relative to the poly-axial head. Embodiments of the second bone anchor assembly may include an anchor, a poly-axial head mated with the second anchor such that the anchor is movable relative to the poly-axial head, a slide ring rotatably mated in the second poly-axial head, and a connector slideably mated in the slide ring along a distal end, and having a proximal end having an enlarged portion. The connector may be movable from a first position axially inline with the second bone anchor to a second position wherein the enlarged portion of the connector rests in the cavity of the first poly-axial head.
