1. A system for external rotational deformity correction of an intact bone comprising:
a first frame member;
a second frame member rotatably coupled to the first frame member;
a first bone fixation member coupled to the first frame member and extending therefrom to couple with a distal segment of the intact bone;
a second bone fixation member coupled to the second frame member and extending therefrom to couple with a proximal segment of the intact bone at a first initial angle relative to the first bone fixation member;
an automated control mechanism coupled to the first frame member and the second frame member; and
a power source configured to provide power to the automated control mechanism,
wherein the automated control mechanism is configured to:
receive power from the power source;
rotate the first frame member to a desired relative rotational position with respect to the second frame member; and
position the first bone fixation member at a desired second angle relative to the second bone fixation member to exert torsional force on the intact bone between the distal segment and the proximal segment, and externally reduce rotational deformity of the intact bone.
