GENERALLY THE THREADED EXTERNAL FIXATOR IS USED FOR FIXATION OF COMPOUND FRACTURES WHICH ARE ACCOMPANIED BY LARGE LACERATED WOUNDS IN NEED FOR DAILY CARE UNTIL COMPLETE HEALING. THE TRADITIONAL EXTERNAL FIXATOR IS COMPOSED OF THREE COMPONENTS, ROD OR LONG TUBE, FIXATION SCREWS AND CLAMP TO HOLD THE SCREW TO THE ROD AND THIS CAUSES SOME DIFFICULTY IN USE ADDED TO THE HEAVY WEIGHT. THE THREADED EXTERNAL FIXATOR IS COMPOSED OF LONG THREADED ROD WITH PENETRATING PERPENDICULAR HOLES FOR PASSAGE OF THE FIXATION SCREWS THAT HOLDS IN PLACE BY TIGHTENING OF THE ADJACENT NUTS ROLLING DIRECTLY OVER THE THREADED ROD , LEADING TO SIMPLICITY OF USE AND ULTIMATELY LIGHT WEIGHT OF THE FIXATOR
