The present invention relates to a jig for derotation screw fixation in trochanteric fractures and a method for the fixation of guide wire for fixing an additional 6.5 mm c.c. screw through said jig. A jig according to the present invention has a handle and a body attached to the handle, said body having a barrel for mounting on a pre-fixed screw shaft and a knob having plurality of holes positioned parallel to said barrel for placing a guide wire through the jig parallel to the first screw. The barrel is positioned at a right angle position to the body. The barrel holds the shaft of the first placed screw. The time required by the surgeon to fix the additional second screw is considerably reduced, thereby reducing the surgery time. The Jig enables fixing an additional screw exactly parallel to the first Richard"s screw that is first fixed.
