1. A method for applying a corrective force to a spinal column, the method comprising the steps of:
advancing a first bone anchor through a proximal cortical wall of a first vertebral body of a spinal column and into the first vertebral body;
compressing cancellous bone within the first vertebral body in a region distal of the first bone anchor by advancing the first bone anchor within the first vertebral body to form a compressed bone region distal of the first bone anchor; and
extending the compressed bone region distally of the first bone anchor by advancing the first bone anchor until the compressed bone region contacts a distal cortical wall opposite from the proximal cortical wall, wherein the step of extending the compressed bone region distally of the first bone anchor by advancing the first bone anchor until the compressed bone region contacts a distal cortical wall increases a fixation strength of the first bone anchor within the first vertebral body.
