A system for aligning vertebrae in the amelioration of aberrant spinal column deviation conditions comprising: a first set of pedicle screws, each pedicle screw having a threaded shank segment and a head segment; and a first pedicle screw cluster derotation tool, said first pedicle screw cluster derotation tool having a first handle means for facilitating simultaneous application of manipulative forces to said first set of pedicle screws and a first group of three or more pedicle screw engagement members which are mechanically linked with said first handle means, said first handle means having a handle linked to each pedicle screw engagement member of the first group of three or more pedicle screw engagement members and a linking member to join together the handles linked to the pedicle screw engagement members, wherein the handle means is configured to move simultaneously each pedicle screw engagement member; wherein each pedicle screw engagement member is configured to engage respectively with said head segment of each pedicle screw of said first set of pedicle screws; and wherein each pedicle screw engagement member is configured to transmit manipulative forces applied to said first handle means to said head segment of each pedicle screw of said first set of pedicle screws; a second set of pedicle screws, each pedicle screw having a threaded shank segment and a head segment; a second pedicle screw cluster derotation tool, said second pedicle screw cluster derotation tool having a second handle means for facilitating simultaneous application of manipulative forces to said second set of pedicle screws and a second group of three or more pedicle screw engagement members which are mechanically linked with said second handle means, said second handle means having a handle linked to each pedicle screw engagement member of the second group of three or more pedicle screw engagement members and a handle linking member to join together the handles linked to the pedicle screw engagement members, wherein the handle means is configured to move simultaneously each pedicle screw engagement member; wherein each pedicle screw engagement member is configured to engage respectively with said head segment of each pedicle screw of said second set of pedicle screws; and wherein each pedicle screw engagement member is configured to transmit manipulative forces applied to said second handle means to said head segment of each pedicle screw of said second set of pedicle screws; a cross-linking member that links the first handle means to the second handle means. view more

The system of claim 2 further comprising a spinal rod member, wherein one or more of said pedicle screws each includes: a spinal rod conduit formed substantially transverse of the length of each said pedicle screw and sized and shaped for receiving passage of said spinal rod member therethrough; and spinal rod engagement means for securing each said pedicle screw and said spinal rod, when extending through said spinal rod conduit, in a substantially fixed relative position and orientation. view more

The system of claim 3 wherein the spinal rod is precontoured.
