Abstract: A method for placing screws in an orthopedic nail used in setting fractures of the long bones of the body. A fluoroscope assembly is used initially to develop an image on a monitor. This image enables the physician to adjust the fluoroscope assembly until the x-rays from the fluoroscope are propagated along lines which are coaxially aligned with the nail screw holes. This status of alignment is then used to allow reference marks to be made on the skin located on one or more lines projected through the limb containing the fractured bone in coaxial alignment with the nail screw holes.The limb is then incised at the location of one or more of these alignment marks allowing tubular drill guides of a jig to be set against the bone in a position of coaxial alignment with the screws holes through the nail.
