Abstract

A spinal system yields a triangular construct across a vertebral body and a quadrilateral construct between vertebral levels. A first pair of screws are engaged in a vertebra on opposite sides of the spinal midline. A longitudinally splined rod, bent into a V-shape, spans between the pair of screws with its vertex generally at the spinal midline. An eyebolt fastener includes a serrated aperture to receive the transverse splined rod, and a threaded post extending through a yoke in the screws. A nut engages the post to clamp eyebolt, rod and yoke together. A second set of fasteners is provided to engage a pair of rigid plates to the transverse rod, each plate spanning between two vertebral levels on either side of the spinal midline. The other end of each plate is engaged to a similar triangular rod construct in the adjacent vertebra.
