Abstract
A compression locking variable length cross-link device having modular components, including rod and/or pedicle screw coupling elements each having a hole which may be disposed co-linearly with respect to other such holes in opposing elements such that a threaded hinge-post may be inserted therein. A nut is utilized to compress the elements together to rigidly secure the elements once they have been properly positioned relative to one another. In an additional set of embodiments, a linkage member having an elongate hole therein may be used to couple similar elements thereto in a similar flexible hinge-post manner such that the elements may be coupled to the linkage member instead of to the opposing elements directly.
