ABSTRACT:
An intramedullary rod system includes a guide rod and a tubular hollow intramedullary rod having an interior surface shaped, at least in a portion, complementary to that of the guide rod. The guide rod is first inserted through the medullary canal and then removed after sliding the tubular intramedullary rod over the guide rod. The guide rod is then aligned outside of the leg parallel to the hollow intramedullary rod for engagement at a distal end by bifurcated prongs with a drill bolt with which bifurcated prongs of the hollow intramedullary rod is simultaneously engaged. Screw holes are thereby aligned between the guide rod and the intramedullary rod at the distal end of the bone without the use of targeting. The hollow intramedullary rod is aligned with the guide rod by a lateral guide for accurate insertion through the guide rod of screws at the distal end of the hollow intramedullary rod.
