ABSTRACT:
A method of forming a beaded transfixion wire for orthopedic uses. The beaded transfixion wire includes an elongated wire formed of an implant grade material. A bead is provided on the elongated wire intermediate the opposite ends thereof. The bead extends outwardly beyond the outer surface of the elongated wire and is integral therewith.
In forming the beaded transfixion wire the solid bar stock is rotatably fed past a cutting tool to turn down a portion of the bar stock to a selected daiameter to provide a first portion of an elongated wire. The first portion of the elongated wire is fed into a tube for stabilizing the first portion against any whipping motion. The solid bar stock is continued to be rotated past the cutting tool while at the same time a bead is profiled from the solid bar stock with the cutting tool. After the bead has been formed in the bar stock another portion of the bar stock is turned down to the selected diameter to provide a second portion of the elongated wire having the selected diameter.
