1. An external fixation frame system comprising:
a first fixation ring configured to be positioned adjacent a first section of a bone of a patient;
a second fixation ring configured to be positioned adjacent a second section of the bone, wherein the first section of the bone is one of a superior or inferior section of the bone, and the second section of the bone is the other of the superior or inferior section of the bone;
a first pin configured to couple the first fixation ring to the first section of the bone;
a second pin configured to couple the second fixation ring to the second section of the bone;
a plurality of adjustable-length struts configured to couple the first fixation ring to the second fixation ring; and
a ring extender, the ring extender having a first linear portion defining a first hole, a second linear portion defining a second hole, and a transverse section coupling the first linear portion to the second linear portion;
wherein in an assembled condition of the external fixation frame system, the first linear portion of the ring extender is directly coupled to the first fixation ring via a first fastener passing through the first hole and into the first fixation ring so that the second linear portion and second hole extend radially outward of the first fixation ring, and at least one of the plurality of adjustable-length struts has a first end directly coupled to the second fixation ring and a second end directly coupled to the second linear portion of the ring extender via a second fastener passing through the second hole,
wherein in the assembled condition of the external fixation frame system, the first linear portion of the ring extender sits directly on top or on bottom of the first fixation ring, and
wherein in the assembled condition of the external fixation frame system, the second linear portion of the ring extender is radially aligned with the first fixation ring.
