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.
