1. A strut assembly for an external fixation system, comprising:
an axially-elongated tubular first strut body;
an elongate intermediate member being rotatably fixed and axially translatably received within the first strut body and axially extending therefrom;
an externally threaded rod within the intermediate member being rotatably and axially fixedly coupled thereto;
an axially-elongated tubular second strut body being received within the intermediate member, wherein the rod is rotatably coupled within the second strut body, and the second strut body axially extends from the intermediate member;
a first adjustment mechanism configured to selectively axially fix the intermediate member relative to the first strut body or selectively allow the intermediate member to freely axially translate relative to the first strut body; and
a second adjustment mechanism configured to selectively rotate the second strut body with respect to the intermediate member and the rod to selectively axially translate the second strut body relative to the intermediate member and the rod.
