ABSTRACT:
A targeting device for making holes in cortical bone for bone nails has a right angle drill which interconnects to a telescopic guide member. The guide member attaches to the drill at the side thereof opposite the chuck. The free end of the telescopic guide attaches to an X-ray machine and maintains the drill in position during the drilling operation. A manual targeting device is used to locate bores in the bone nail and to spot drill the bone. The aligned telescopic guide is then used to complete the drilling operation.
