Abstract: An apparatus and method for the treatment of abnormal spinal curvature, such as, scoliosis, is disclosed. The apparatus includes a plurality of clamp sets and a single rail. The clamp set for affixing to a vertebra has a transverse plate having a center region and a first and a second end. The first end has a first pedicle extension, and the second end has a second pedicle extension. At least one pedicle extension is used to transmit a downward force during rotation of the vertebra. The clamp set also includes a first laminar hook located on the first end of the plate and is integral with the plate to hook on a superior portion of a first lamina of a vertebra. The clamp set also includes a second laminar hook to hook from an opposite direction on an inferior portion of a second lamina of the vertebra. The second hook is adjustable to allow clamping and unclamping of the clamp set. The clamp set includes a rail coupling member having a slot to receive a rail.

Abstract: A spinal fixation system comprises a pair of facet screws that extend through the facet joint from the inferior facet of a superior vertebra and into the base of the transverse process of the immediately inferior vertebra. A pair of stabilizing bars are operatively coupled to the screws adjacent their heads. The bars carry fingers that extend in a superior direction and loop over the superior aspect of the pedicle of the superior vertebra. The stabilizing bars thus stabilize the facet screws and prevent their tendency to toggle, thereby conjunctively stabilizing the superior vertebra to the immediately inferior vertebra, for example, to facilitate the healing of a fusion.

Abstract: A sacral implant system includes first and second sacral plates that are affixed on opposite sides of the sacrum adjacent the lumbosacral junction. The sacral plates include at least a pedicle and an oblique mounting means for rigidly affixing the sacral plates to the sacrum. First and second fixation rods extend in a superior direction along the lumbar portion of the spine. One or more connecting members tie the rods together. The superior most vertebra to be fixed is tied to the implant system with a special offset fixation plate and pedicle screw. Conventional vertebra hooks can also be used as necessary. Intermediate vertebra are tied to the system with a straight fixation plate and pedicle screw.
