ABSTRACT:
A method of correcting spinal deformities and a spinal fixation system for use in the method. After surgically exposing the spine posteriorly, a series of clamps are affixed to the laminae of the vertebrae. Beginning at either end of the line of clamps, a rod attachment device is attached to each affixed clamp. Again, beginning at either end of the line, a rod is inserted into the rod attachment devices. Compression or distraction is then applied to the spine between successive vertebrae proceeding from one clamp to the next until all clamps are secured to the rod.
