ABSTRACT:
The telescoping rod to rod coupler of this invention substantially eliminates the chances of the two rod sections disconnecting from one another by providing a relief in the male section to define a hook shaped end. The hook shaped end in association with a clamping screw carried by the female section requires the rod sections to axial rotate 180 degrees in a screw-like manner during assembly and disassembly. The clamping screw constitutes an abutment or stop for engagement with the hook shaped end to provide a positive stop to prevent the sections from accidentally sliding past their extremes and out of engagement with one another during the surgery. Further, the reliefs provided within the male telescoping section, permit the two rod sections to be firmly affixed to one another with one section axially rotated slightly relative to the other rod section.
