1. A system for applying a manipulative force to a target region of a spinal column during a surgical procedure, the system comprising:

  • a first pedicle screw having a proximal portion and a distal portion, the distal portion of the first pedicle screw being configured to be implanted into a first pedicle of a first vertebra;

    a second pedicle screw having a proximal portion and a distal portion, the distal portion of the second pedicle screw being configured to be implanted into a second pedicle of the first vertebra;

    a third pedicle screw having a proximal portion and a distal portion, the distal portion of the third pedicle screw being configured to be implanted into a first pedicle of a second vertebra;

    a fourth pedicle screw having a proximal portion and a distal portion, the distal portion of the fourth pedicle screw being configured to be implanted into a second pedicle of the second vertebra;

    a first elongated lever having a proximal portion and a distal portion, the distal portion of the first elongated lever being configured to temporarily engage with and provide leverage itself to the proximal portion of the first pedicle screw;

    a second elongated lever having a proximal portion and a distal portion, the distal portion of the second elongated lever being configured to temporarily engage with and provide leverage itself to the proximal portion of the second pedicle screw;

    a third elongated lever having a proximal portion and a distal portion, the distal portion of the third elongated lever being configured to temporarily engage with and provide leverage itself to the proximal portion of the third pedicle screw;

    a fourth elongated lever having a proximal portion and a distal portion, the distal portion of the fourth elongated lever being configured to temporarily engage with and provide leverage itself to the proximal portion of the fourth pedicle screw;

    a linking member configured to link at least two of the elongated levers in a axial direction such that they move in unison; and

    a cross-linking member configured to link at least two of the elongated levers in a transverse direction such that they move in unison,wherein the system, when assembled, permits an operator to move the first, second, third and fourth elongated levers in unison to simultaneously rotate the first, second, third and fourth pedicle screws about a spinal column roll axis.
