Abstract:
1. A method for correcting a deformity of a spinal column comprising: implanting a plurality of bone screws into a plurality of vertebrae of a spinal column; mounting rod reduction jacks to at least some of the plurality of bone screws; inserting a spinal rod between the rod reduction jacks and the bone screws; partially actuating the rod reduction jacks to gradually reduce the spinal rod to each bone screw while effecting realignment of the vertebrae relative to one another; removing the rod reduction jacks from a first side of the spinal column; repeating the above steps on a second side of the spinal column; and with the spinal rods partially locked in the bone screws, facilitating sagittal alignment of the spinal rods, wherein one portion of each of the rods is anchored to vertebrae, including a lowest instrumented vertebra, using polyaxial screws and the remaining portion of each of the rods is anchored to the vertebrae using uniplanar taper lock bone screws with the lowest instrumented vertebra anchored to the rods using monoaxial bone screws.
