Abstract: A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.

Abstract: A system for external rotational deformity correction of an intact bone may include: a first frame member and a second frame member rotatably coupled therewith, a first bone fixation member coupled to the first frame member and to a distal segment of the intact bone, a second bone fixation member coupled to the second frame member and to a proximal segment of the intact bone at a first angle, an automated control mechanism coupled to the first and second frame members, and a power source for the automated control mechanism. The automated control mechanism may: receive power from the power source, rotate the first frame member to a desired relative rotational position, and position the first bone fixation member at a desired second angle to exert torsional force on the intact bone and externally reduce rotational deformity of the intact bone.

Abstract: An apparatus and method for external anteversion correction of an intact bone may include 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 and second arcuate segments. The control mechanism may rotate the first arcuate segment relative to the second arcuate segment to exert torsional force on the intact bone between the proximal and distal segments of the intact bone, thereby externally reducing anteversion of the intact bone.
