Abstract: A spinal fixation system suitable for effecting fixation between adjacent vertebral levels within the spine. The spinal fixation system of the present invention includes a pair single axis or “fixed” pedicle screw assemblies, a pair of poly-axial pedicle screw assemblies, a pair of cannulated rod members, and a transverse connector spanning between the pair of cannulated rod members.

Abstract: Systems and methods for a guide assembly for introducing a bone anchor to an operative target site. The guide includes an outer sleeve and an inner sleeve. The outer sleeve has a distal anchor engaging end, a proximal end, and a central passage extending from the distal end to the proximal end. The inner sleeve may be situated in the central passage of the outer sleeve. The inner sleeve is movable being between a first position and a second position. The first position permits insertion of the bone anchor in the central passage. The second position releasably fixes the bone anchor to the guide assembly.

Abstract: A spinal distraction assembly is provided for distracting the disc space between a pair of vertebrae, the vertebrae each having been implanted with a bone anchor. The spinal distraction assembly includes a first anchor engaging element and a second anchor engaging element. The first anchor engaging element includes a body having a channel extending through the longitudinal axis of the body. The second anchor engaging element includes a guide bar. The guide bar is dimensioned to translate through the body channel. Anchor engaging arms extend laterally from each of the body and guide bar.
