Abstract
The present invention relates to a transverse connector having an assembly, which joins two spinal rods to form a spinal implant construct. The transverse connector has two members each having terminal clamping members such as opposing rod recesses each having a biasing setscrew, which locks the rod into position in the recess. The first of the two members has a bore, which receives the cylindrical extension of the other part so that it can move inward and outward and rotate in the bore. Further, the connector has a limiting mechanism, which comprises a vertical keyway which receives and captures the flanged end of the extension in a slot having opposed undercut areas so that the flanged end can be inserted into the keyway and slid downward toward the bore. The extension further has a second flanged area in order to avoid over-insertion of the second member into the first member.
