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: A cap for a c-arm medical imaging device with an image intensifier comprises a plate sized and shaped to cover an exterior facing surface of the image intensifier. The plate is transparent to x-rays and has a planar center with a planar outer surface and a planar inner surface to face the image intensifier. A retainer is carried by the plate to retain the plate on the image intensifier.
