7. An apparatus configured to apply an external torsion force to an intact bone comprising:
a first arcuate segment;
a second arcuate segment rotatably coupled to the first arcuate segment;
a first pin extending from the first arcuate segment to a proximal segment of the intact bone;
a second pin extending from the second arcuate segment to a distal segment of the intact bone; and
a control mechanism attached to the first arcuate segment and to the second arcuate segment;
wherein the control mechanism enables fixation of the second arcuate segment in any of a plurality of orientations relative to the first arcuate segment to control an orientation of the first pin with respect to the second pin to exert torsional force on the intact bone between the proximal segment and the distal segment, thereby externally reducing anteversion of the intact bone.
