An orthopedic fixation system having two rings or other base/frame elements separated by a plurality of struts. The struts are attached to the rings by a combination of a attachment mechanism having at least two degrees of movement each, and at least one connecting mechanism. The connecting mechanisms may be moveably or non-moveably connected to one or more tracks located on either or both rings of base elements. A combination of these elements provides a fixation device that allows for six degrees of freedom of movement between the rings or other base elements.
